y = 46
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
x equals -12 and y equals 1/4 of -12, so y = -3.

y = 12. It's the transitive property. y = 12 = 3x.
12 = 24-y then y = 12

-6/y=5/-2 5y=12 y=12/5
x = 6 and y = -2
x=6 y=30
12
3x - y = 12 is the same as 3x - 12 = y, or y = 3x - 12.
