For each part A through D below, the idea is to find the common factor between the terms, which you'll then use the distributive property to pull out.

==================================

Part A

3x + 18 = 3(x+6)

Note how we pulled out a 3. If we distribute it back in, we end up with 3x+18 again. The other problems are done in a similar fashion

==================================

Part B

2x - 14 = 2(x - 7)

==================================

Part C

6x + 4 = 2(3x + 2)

==================================

Part D

9x - 15 = 3(3x - 5)
