Y = 4x + 11

y = - 2x - 1

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
