1) 42 = 2b - 14 ---> solve for b

2) b = 3 + 4g ---> solve for g

3) x + y = 84

x = 12 + y ---> solve for x and y

4) x + x + 1 = 37 ---> solve for x and x + 1

5) x = 10 + y

2y + 3x = 55 ---> solve for x and y

6) x + 2x + (2x - 5) = 80

7) one person paints a wall in 23 minutes; so, how long will it take 9 persons to paint 9 walls?

8) P = 2l + 2w

l = 3w ---> solve for l and w

P = 104

In one minute, the 6 people will paint 6/23 of a wall

So....in one minute....one person will paint 1/23 of a wall

So.....9 people will paint 9/23 of a wall in one minute

So.....in 23 minutes.....they will paint 9 walls
