Solve the system of equations: Rewrite this as: and substitute for x in the second equation. Simplify and solve for y. Combine like-terms. Subtract 30 from both sides. Finally, divide by -7. Now substitute this for y in the first rewritten equation and solve for x:
So the solution is: (-2, 4)
The graph of these two lines is shown below, and the point at which the lines intersect is called the solution.
