1. 4b - 2 : the product of 4 and a number (b) decreased by 2

2. the sum of 15 and 4 times a number ... 15 + 4x

3. 8 fewer boys then girls ... how many boys ... b = g - 8

4. It will be less then 1 because of the negative exponent ... a negative exponent will mean the number is less then 1 ... I dont really know how else to explain it.

5. Doug is twice Anna's age ... doug is 34 years old

I dont know the 5 step plan ... but I am putting what I do know

d = doug's age

a = anna's age

d = 2a

d = 34

34 = 2a

34/2 = a

17 = a ... so anna is 17

check ...

d = 2a

d = 2 (17)

d = 34 (correct)
