Question

Solve for c.

a(b-c)=d

(make an equation that solves c)
solve for f.c=8 π

fb

Answer 1

a(b-c)=d solve for c

divide both sides by a

b-c = d/a

subtract both sides by b

-c = d/a - b

divide both sides by negative 1

c = -d/a + b

c = b - d/a

------

c=8πfb solve for f

divide both sides 8πb

c/8πb = f

or

f = c / 8πb
