find x :
m%2Fc+-+3a+%2B+c%2Fx+=+f
:
Get rid of the denominators, mult eq by cx
mx - cx(3a) + c(c) = cx(f)
:
mx - 3acx + c^2 = cfx
:
GEt all the terms containing x on the left by itself:
mx - 3acx - cfx = -c^2
:
Factor out x:
x(m - 3ac - cf) = -c^2
:
divide both sides by (m-3ac-cf):
x = -c%5E2%2F%28m-3ac-cf%29
