You solve equations with decimals the same way that you solve equations with integers.

3.9w - 17.9 = -2.3

Step 1: Add 17.9 to both sides.

3.9w - 17.9 + 17.9 = -2.3 + 17.9

3.9w = 15.6

Step 2: Divide by 3.9 on both sides.

3.9w/3.9 = 15.6/3.9

w = 4

Your final answer is 4.

Hope this helps,
Karin
