Elimination Method:
\The equations are
\ Equation (1)
Equation (2)
Multiply the first equation by 3.
\ Equation (3)
Since the coefficients of the x-terms are additive inverses, you can eliminate these terms by subtracting the equations. Subtract the equations to eliminate variable x.
\Write the equations in column form and add the corresponding columns.
\Now, find the x value by substituting in either equation.
(Equation 2)
Add 17.5 to each side.
\Divide each side by 1.2.
\The solution is .
