Elimination Method:

The equations are $\"\"$ and $\"\"$ .

$\"\"$ Equation (1)

$\"\"$ Equation (2)

Multiply by 2 in first equation.

$\"\"$

$\"\"$ Equation (3) $\"\"$

Since the coefficients of y-terms are additive inverses, these terms can be eliminated by subtracting equations. Write the equations in column form and subtract the corresponding columns.

$\"\"$

Find the y, substitute $\"\"$ in first equation.
