Question

Given 7cx + b = a, rearrange the equation for x, in terms of a, b, and c.

Answer 1

Already in terms of a
Term b = 7cx - a = b
Term c = 7x + a - b = c

Answer 2

Actually, you want to rearrange the given equation to solve for x:

7cx + b = a

Let's isolate 7cx by subtracting b from both sides of this equation:

7cx = a - b

Then x = (a - b) / (7c)
