**Pam**, Friday, May 16, 2008 at 10:33amOops....sorry, I forgot to put the problem in.

-2y = 228 + 8x

10x + 11y = -64

Solve each system of equations using the substitution method.

**bobpursley**, Friday, May 16, 2008 at 1:41pmPut them in standard form:

8x+2y=-228

10x+11y=-64

Elminate a variable. I will pick x. Multiply the top equation by 10, the second equation by 8

80x+20y=-2280

80x+88y=-64*8

now subtract the second equation from the first..

-68y=-2280+64*8

and proceed to solve for y. Then, substitue back in the original equation, either one, and solve for x.
