For the following system, if you isolated y in the first equation to use the Substitution Method, what expression would you substitute into the second equation? 2x + y = 8 -x - y = -5 Answer -8 - 2x -8 + 2x 8 + 2x 8 - 2x
So, isolate y in the first equation and what do you get? If you only had the first equation and you were trying to solve for y, what would you do?
Yes, the only thing you have to do to get y by itself is subtract 2x from both sides.
