y = -2x + 19
y = x + 7
Since both equations are solved for y, set them equal to each other and solve for x.
x + 7 = -2x + 19
Add 2x to both sides.
3x + 7 = 19
Subtract 7 from both sides.
3x = 12
Divide both sides by 3.
x = 4
Now substitute 4 for x in the first original equation to find y.
y = -2(4) + 19
y = -8 + 19
y = 11
Answer: x = 4 and y = 11
