Question

cx+b =3(x-c)
cx+b =3x-3c
I don't know what to do next..

Answer 1

Hmm perhaps break into two equations, cx=3x and b=-3c

Answer 2

how would I do that? it's solve for x

Answer 3

Ahh well in that case, probably need to see the original question.

Answer 4

or are you just asked to find the symbolic answer

Answer 5

If just symbollic, collect the terms with x on one side, and the ones without on the other side.

Answer 6

i.e subtract 3x from both sides and subtract b from both sides

Answer 7

like making it into -2x +cx = -3c -b ?

Answer 8

yes if the first term was -3x

Answer 9

so -3x+cx=-3c-b

Answer 10

next factor x out on the left side

Answer 11

solving for x?

Answer 12

Yes
factoring out x
x(c -3) = - 3c - b

Now divide both sides by c - 3

Answer 13

x = -3c -b / c- 3 ... ?
