For the following system, if you isolated x in the first equation to use the Substitution Method, what expression would you substitute into the second equation? (5 points)
-x + 2y = -6
3x + y = 8

-2y + 6
2y - 6
2y + 6
-2y - 6

wait what

faiqraees · Answer

pick the first equation and make x the subject

ilovepuppieslol · Answer

so i substitue 6 into x?

faiqraees · Answer
