Question

Cx/a+f=b solve for x

Answer 1

(cx/a) + f = b

isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract f from both sides

(xc/a) + f (-f) = b (-f)

xc/a = b - f

Next, multiply a to both sides

(xc/a)a = (b-f)a

Distribute a to all terms within the parenthesis

xc = ab - a(f)

Finally, to isolate the x, divide c to both sides

(xc)/c = (ab - a(f))/c

x = (ab - a(f))/c

x = (ab - a(f))/c is your answer

hope this helps
