Question

Solve the system of equations by either the addition method or the substitution method. Show your work. Check your solution.
			y = –3x + 11
			–6x + 6y = –6

texaschic101 · Answer

Well, you already know what y equals...it equals -3x + 11. Now sub -3x + 11 in for y in the second equation...
-6x + 6y = -6
-6x + 6(-3x + 11) = - 6
Distribute the 6 through the parenthesis. Then combine like terms. Next, get x on one side and everything else on the other side. Then solve for x. Can you take it from here ?
