$y + x = - 2$ , $2 = y - 2 x$

Step 1

Subtract $x$ from both sides of the equation.

$y = - 2 - x$

$2 = y - 2 x$

Step 2

Rewrite the equation as $y - 2 x = 2$ .

$y - 2 x = 2$

$y = - 2 - x$

Step 3

Add $2 x$ to both sides of the equation.

$y = 2 + 2 x$

$y = - 2 - x$

Step 4

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.

$(- \frac{4}{3}, - \frac{2}{3})$
