11-80.
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

$x=\frac{a+b}{c}$

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.
