1. 5-8b+6-2B=61

2. 4x-6-8x-9=21

3. g-9+4g+6=12

4. 2-3f-5+5f=6

Combine like terms:

-8b - 2b = 61 - 5 - 6

-10b = 50

b = -5

Follow this pattern to solve the other problems. We'll be glad to check your answers.

**Sara!**, Monday, May 31, 2010 at 12:47pmfor #2 i keep getting the answer -4.5 and i check and its wrong this is what i did

4x-8x=-4x

6-9=-3

-4x--3=21

18=21

x=-4.5

are the steps i did wrong and when i plug in the number i get 3 as an answer instead of 21

**Ms. Sue**, Monday, May 31, 2010 at 1:16pmAs a non-mathematician, I get confused by a lot of numbers, too. <g> But here's the way to do 2.

4x-6-8x-9=21

-4x - 6 - 9 = 21

-4x = 21 + 15

x = -9

The answer for number 3 is 3. Can you keep working this problem until you get the right answer?

**Ms. Sue**, Monday, May 31, 2010 at 1:36pmWhen you do the problem or the proof, please be sure you don't leave out any parts of the original problem. (I kept leaving a part of the original problem out until I went back and triple checked.)
