Solve for xx: ax+b=cax + b = c

A

x = (c - b) / a

B

x = (c + b) / a

C

x = (b - c) / a

D

x = c - b - a

Correct Answer: A

Choice Choice A is the correct answer.

  1. Start: ax+b=cax + b = c
  2. Subtract b: ax=c−bax = c - b
  3. Divide by a: x=c−bax = \frac{c - b}{a}

Choice Choice D is incorrect because subtracted a.

Choice Choice B is incorrect because sign error.

Choice Choice A is incorrect because sign error.
