x = - 2, y = 3
Step-by-step explanation:
y = 4x + 11
y = - 2x - 1
Because both equations are equal to y, we can set them equal to each other
4x + 11 = - 2x - 1
Add 2x to each side
4x+2x + 11 = - 2x+2x - 1
6x + 11 = - 1
Subtract 11 from each side
6x+11-11=-1-11
6x = - 12
Divide each side by 6
6x/6 = - 12/6
x = - 2
Now we need to find y
y = - 2x-1
y = - 2 (-2) - 1
=4-1
=3
