Solve by substitution or elimination method?

Question

3x - 27 = 8

-12x + 8y = 32

Answer 1

substitution you can't do elimnation because there is no value for y, so solver for x on the first problem then just plug it in to the second problem and solver for y.

Answer 2

-12(x - 27) = -12 * 8

-12x + -324 = -96

-12x + 8y    =  32

         -316  =  -128

                2.4
