(50 points) could someone me with this? part a: solve –mk – 90 > 85 for m. part b: solve 3c – 5f = 55 for f. show your work for both but don't make it too complicated.

A:

-mk - 90 > 85

-mk - 90 + 90 > 85 + 90

-mk > 175

-mk / k > 175 / k

-m > 175/k

-m * -1 < 175/k * -1

m < -175/k

Part B:

3c - 5f = 55

3c - 5f - 3c = 55 - 3c

-5f = 55 - 3c

-5f/5 = (55 - 3c) / 5

-f = 55/5 - 3c/5

90>85

Step-by-step explanation:

answer: 45
