Elimination Method:
The equations are
\ Equation (1)
Equation (2)
Multiply by 2 in first equation.
\ Equation (3)
Since the coefficients of x-terms are additive inverses, these terms can be eliminated by subtracting equations.
\Write the equations in column form and subtract the corresponding columns.
\Divide each side by 11.
\Now, find the y value by substituting in either equation.
(Equation 2).
Subtract 5 from each side.
\Divide each side by 4.
\The solution is .
