Question

Solve C = 3(2f – 5h) for f in terms of C and h. You must show all work.

Answer 1

C = 3(2f - 5h)
To solve for f means to isolate f.
First we distribute 3 on the right side:
C = 3(2f) - 3(5h)
C = 6f - 15h
Now that we have f in a sinlge term, let's get rid of -15h by adding 15h to both sides
C + 15h = 6f
Switch sides:
6f = C + 15h
Since f is being multiplied by 6, we divide both sides by 6:
f = (C + 15f)/6
