Rogelio Coffey · Answer 1

you can plug in for variables, so if x = 3, then 4x = 12, because 4x = 4 (3) : this is the "substitution" property ... If x + 2 = 10, then x + 2 + (-2) equals what, and why? ... to solve it, I'd have subtracted 2 from both sides, and simplified to get x = 8.

If 3x5 is 15, then X=15
