7x+4y=1461920290375446110677,5x-2y=19

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

7x+4y=1461920290375446110677

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

7x=-4y+1461920290375446110677

Subtract 4y from both sides of the equation.

x=\frac{1}{7}\left(-4y+1461920290375446110677\right)

Divide both sides by 7.

x=-\frac{4}{7}y+\frac{1461920290375446110677}{7}

Multiply \frac{1}{7} times -4y+1461920290375446110677.

5\left(-\frac{4}{7}y+\frac{1461920290375446110677}{7}\right)-2y=19

x=\frac{1461920290375446110715}{17},y=\frac{3654800725938615276626}{17}

The system is now solved.

7x+4y=1461920290375446110677,5x-2y=19

Put the equations in standard form and then use matrices to solve the system of equations.

\left(\begin{matrix}7&4\\5&-2\end{matrix}\right)\left(\begin{matrix}x\\y\end{matrix}\right)=\left(\begin{matrix}1461920290375446110677\\19\end{matrix}\right)

Write the equations in matrix form.

inverse(\left(\begin{matrix}7&4\\5&-2\end{matrix}\right))\left(\begin{matrix}7&4\\5&-2\end{matrix}\right)\left(\begin{matrix}x\\y\end{matrix}\right)=inverse(\left(\begin{matrix}7&4\\5&-2\end{matrix}\right))\left(\begin{matrix}1461920290375446110677\\19\end{matrix}\right)

Left multiply the equation by the inverse matrix of \left(\begin{matrix}7&4\\5&-2\end{matrix}\right).

\left(\begin{matrix}1&0\\0&1\end{matrix}\right)\left(\begin{matrix}x\\y\end{matrix}\right)=inverse(\left(\begin{matrix}7&4\\5&-2\end{matrix}\right))\left(\begin{matrix}1461920290375446110677\\19\end{matrix}\right)

The product of a matrix and its inverse is the identity matrix.

\left(\begin{matrix}x\\y\end{matrix}\right)=inverse(\left(\begin{matrix}7&4\\5&-2\end{matrix}\right))\left(\begin{matrix}1461920290375446110677\\19\end{matrix}\right)

Multiply the matrices on the left hand side of the equal sign.

\left(\begin{matrix}x\\y\end{matrix}\right)=\left(\begin{matrix}-\frac{2}{7\left(-2\right)-4\times 5}&-\frac{4}{7\left(-2\right)-4\times 5}\\-\frac{5}{7\left(-2\right)-4\times 5}&\frac{7}{7\left(-2\right)-4\times 5}\end{matrix}\right)\left(\begin{matrix}1461920290375446110677\\19\end{matrix}\right)

For the 2\times 2 matrix \left(\begin{matrix}a&b\\c&d\end{matrix}\right), the inverse matrix is \left(\begin{matrix}\frac{d}{ad-bc}&\frac{-b}{ad-bc}\\\frac{-c}{ad-bc}&\frac{a}{ad-bc}\end{matrix}\right), so the matrix equation can be rewritten as a matrix multiplication problem.

\left(\begin{matrix}x\\y\end{matrix}\right)=\left(\begin{matrix}\frac{1}{17}&\frac{2}{17}\\\frac{5}{34}&-\frac{7}{34}\end{matrix}\right)\left(\begin{matrix}1461920290375446110677\\19\end{matrix}\right)

Do the arithmetic.

\left(\begin{matrix}x\\y\end{matrix}\right)=\left(\begin{matrix}\frac{1}{17}\times 1461920290375446110677+\frac{2}{17}\times 19\\\frac{5}{34}\times 1461920290375446110677-\frac{7}{34}\times 19\end{matrix}\right)

Multiply the matrices.

\left(\begin{matrix}x\\y\end{matrix}\right)=\left(\begin{matrix}\frac{1461920290375446110715}{17}\\\frac{3654800725938615276626}{17}\end{matrix}\right)

Do the arithmetic.

x=\frac{1461920290375446110715}{17},y=\frac{3654800725938615276626}{17}

Extract the matrix elements x and y.

7x+4y=1461920290375446110677,5x-2y=19

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

5\times 7x+5\times 4y=5\times 1461920290375446110677,7\times 5x+7\left(-2\right)y=7\times 19

To make 7x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 7.

35x+20y=7309601451877230553385,35x-14y=133

Simplify.

35x-35x+20y+14y=7309601451877230553385-133

Subtract 35x-14y=133 from 35x+20y=7309601451877230553385 by subtracting like terms on each side of the equal sign.

20y+14y=7309601451877230553385-133

Add 35x to -35x. Terms 35x and -35x cancel out, leaving an equation with only one variable that can be solved.

34y=7309601451877230553385-133

Add 20y to 14y.

34y=7309601451877230553252

Add 7309601451877230553385 to -133.

y=\frac{3654800725938615276626}{17}

Divide both sides by 34.

5x-2\times \frac{3654800725938615276626}{17}=19
