Solve the system of equations by graphing on your own paper. What is the x-coordinate of the solution?

Dovator [93]

Y = x + 7
<span>y = -2x - 11

x + 7 = -2x - 11
3x + 7 = -11
3x = -18
x = -6

The x-coordinate of the solution is -6.

I have attached a graph of the two equations since the question really wanted you to graph it and then find the answer.</span>
