SILVER said:here is a problem i don't get:
2x+3y=7
-10x-3y=25
its a problem with two unknowns and the answer is x=-4, y=5. I started by adding the two together and got -12x=32 but when i divided that i got -0.37 and the answer ix=-4.HELP!
C'mon Silver...SILVER said:2x+(-10x)=-32 does'nt it? when i divided 32 by -12 i got -2.66. How do i get -4?
