x = y + 6 and x =-3y - 22 x = x y + 6 = -3y -22 4y = -22 - 6 4y = -28 y = -7 x=-7 + 6 = -1 I don't believe this method is what they wanted. (But it works and is the simplest)

Here is the addition method. x - y = 6 now we will add the 2nd equation to the first equation -x-3y = 22 adding we get ------------ -4y = 28 y = -7 now substitute the -7 value for y in the first equation getting x - (-7) = 6 x + 7 = 6 x = 6 - 7 x = -1 Same answers as the first go around.
