$y - 2 x = 0$ $y + x = 3$

Step 1

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

$y = 2 x$

$y + x = 3$

Step 2

Subtract $x$ from both sides of the equation.

$y = 3 - x$

$y = 2 x$

Step 3

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

$(1, 2)$
