$\"\"$

The equations of linear system are $\"\"$ .

Since the coefficient of the x - terms in the above two equations are additive inverse, eliminate these terms by adding the equations.

Write the equations in column form and add to eliminate variable x.

$\"\"$ . $\"\"$

The resultant equation is $\"\"$ and solve it for y.

Divide each side by 1.5.

$\"\"$

Cancel common terms.

$\"\"$ . $\"\"$

Substitute the value of $\"\"$ in equation 1: $\"\"$ and solve for x.

$\"\"$

Add 15 to each side.

$\"\"$

Divide each side by 1.3.

$\"\"$

Cancel common terms.

$\"\"$ . $\"\"$

The solution is $\"\"$ .
