Question

Identify the y coordinate for the solution to the system of equations. Solve the system using substitution.

y=2x-11

4x + 3y =-13

Answer 1

(2,-7)

Explanation:

Plug the first equation into the second equation.

4x+3(2x-11)=-13

4x+6x-33=-13

10x=20

x=2

Now, plug the value of x into one of the equations in order to find y.

y=2(2)-11

y=4-11

y=-7
