Question

solve for x in terms of a,b, and c: ax - 3b =c

1: a(c+3b)
2: a (c-3b)
3: c-3/a
4: c+3b/a

Answer 1

Add 3 to both sides, then divide both sides by 'a' to isolate x


\[\Large ax - 3b = c\]


\[\Large ax = c+3b\]


\[\Large x = \frac{c+3b}{a}\]

Answer 2

*Add 3b to both sides* (not 3)

Answer 3

ok

Answer 4

so i add 3b to what?

Answer 5

Answer 7

ok.....

Answer 8

@jim_thompson5910

Answer 9

then what?

Answer 10

It's already done, look at my first post

Answer 11

so i divide both sides by a?

Answer 12

@jim_thompson5910

Answer 13

yes in that last step

Answer 14

and thats how you got c+3b/a?

Answer 15

exactly

Answer 16

so basically, collect the terms in x on one side of the equation, and the literal terms on the other side @jim_thompson5910

Answer 17

bingo, you want x on its own side (preferably the left) and everything else on the other side

Answer 18

got it, Thanks :) @jim_thompson5910
