**Dr. Jane**, Thursday, March 7, 2013 at 12:47pmUse substitution means replace y in the first equation with what y equals in terms of x.

-5x + 2(2x+11) = 27

Next, multiply by 2 to remove ( )

combine like terms

continues to solve for x.

Find y by replacing x with your answer for x in y = 2x+11

Always...check x and y in both equations.
