(50 points) Could someone help me with this? Part A: Solve –mk – 90 > 85 for m. Part B: Solve 3c – 5f = 55 for f. Show your w ork for both but please don't make it too complicated.
2 answers:
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
