Part A: Solve –vp + 30 < 45 for p. Show your work.

Part B: Solve 3w – 6r = 30 for r. Show your work.

A: -vp + 30 < 45
Subtract 30 from both sides.
-vp < 15
Divide both sides by -v.
p > -15/v
( when dividing a negative, the < sign must be changed to >)
B. 3w - 6r = 30
Subtract 3w from both sides.
-6r = -3w + 30
Divide both sides by -6
r = (-3w + 30)/ -6
simplify the right side

r = (w - 10)/2
OR
r = (-3w/-6) + (30/-6)
r = w/2 - 5
