OpenStudy (vera_ewing):
So first, distribute 4(x-3) That would end up as: 4x-12
OpenStudy (vera_ewing):
So then, you have to isolate the variable, which is x.
OpenStudy (narissa):
why did you have to swich the 12 and the 5?
OpenStudy (vera_ewing):
4x - 12 + 5x = -48 4x + 5x - 12 = -48 4x + 5x - 12 + 12 = -48 +12 4x + 5x = -36 9x = -36 x = -4

Ok, so I switched the 12 and the 5 because we have to get all of the x's on the right side.
