Question

What is the solution set for 7x − 3 =18, given the replacement set {0, 1, 2, 3, 4}?

x = 0

x = 1

x = 2

x = 3

x = 4

Answer 1

x = 3

Explanation:

Let's solve your equation step-by-step.

7x−3=18

Step 1: Add 3 to both sides.

7x−3+3=18+3

7x=21

Step 2: Divide both sides by 7.

7x/7 = 21/7

x=3
