Part A:

Solve - vp + 40 < 65 for v. Show your work

Part B : solve 7w - 3r = 15 for r. Show your work.

v > - 25/p

r = - 5 + 7/3w

Step-by-step explanation:

-vp + 40 < 65

Subtract 40 from each side

-vp + 40 - 40< 65-40

-vp < 25

Divide by - p. Remember to flip the inequality

-vp/-p > 25/-p

v > - 25/p

7w - 3r = 15

Subtract 7w from each side

7w - 7w - 3r = 15-7w

-3r = 15-7w

Divide by - 3

-3r/-3 (15-7w) / -3

r = - 5 + 7/3w
