[6.02] 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? -x - 2y = -4 3x + y = 12
-x=-4+2y Multiply both the sides by -1 to get x x=4-2y
@LoveYou*69 Did you understand it?
Now substitute it in second equation 3(4-2y) + y = 12
Okay! Thanks! and yea ash i knew the answer i was just making sure it was right lol :)
so is the answer -2y+4
