  1. Solve each equation below for x. Show all of your work. (Your answers will contain the variables a, b, and/or c.) Homework Help ✎

    1. cxa = b

    2. b = c

    3. (xa)(xb) = 0

    4. ax2acx = 0

    5. + a = b

x = ab + ac

x = a or x = b

Factor and use the Zero Product Property.

Multiply both sides by c(a + b).

Subtract a from both sides and take the reciprocal of both sides.
