What value will make the equation
6x + 30 = 3x - 42
3x = -42 + (-30)
3x = -72
x = -?
I understand that part but I'm just not sure when the question asks me what VALUE will make the equation TRUE will it be x=-72? because I don't think that's what there asking me.
I don't see what else the question is asking.
The equation is true when you find that x = -24.
Substitute -24 in the original equation to prove that it is the correct value of x.
