y=6x-11
-2x-3y=-7
Take "6x-11" and insert it where it says 3y. Now you have:
-2x-3(6x-11)=-7
Use distributive property (-3 × 6x) ( -3 × -11). Now you have:
-2x-18x+33=-7
Combine like terms. (-2x + -18x). Now you have:
-20x+33=-7
Subtract 33 from both sides (33-33 and -7-33). Now you have:
-20x=-40
Divide -20 from both sides (-20x/20 and -40/-20). Now you have:
Answer: x= 2
