Use substitution to solve the system.

y=2x+11

3x+4y=-11

Substitute 2x + 11 where you see y in the second equation and solve for x.

3x + 4 (2x + 11) = - 11

3x + 8x + 44 = - 11

11x + 44 = - 11

11x = - 55

x = - 5

Now, substitute - 5 where you see x in the first equation and solve for y.

y = 2 (-5) + 11

y = - 10 + 11

y = 1

The answers are x = - 5 and y = 1.
