Elimination Method:
The equations are
\ Equation (1)
Equation (2)
Multiply by 3 in first equation.
\ Equation (3)
Multiply by 2 in second equation.
\ Equation (4)
Since the coefficients of x-terms are additive inverses, these terms can be eliminated by adding equations.
\Write the equations in column form and add the corresponding columns.
\Divide each side by 8.
\Now, find the y value by substituting in either equation.
(Equation 2)
Subtract 12 from each side.
\Divide each side by negative 2.
\The solution is .
