$\"\"$ 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 x value by substituting $\"\"$ in either equation.

$\"\"$ (Equation 2)

$\"\"$

Subtract 5 from each side.

$\"\"$

Divide each side by 4.

$\"\"$

The solution is $\"\"$ .
