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

i really dont know can u help me understand
