Question 1025828: Solve the equation for the indicated variable. Assume all constants are non-zero.
Solving for x, if A does not equal 21 (sorry, I don't have the correct symbol):

(Ax-B)/[C-B(1-3x)]=7

x=

.
%28Ax-B%29%2F%28C-B%281-3x%29%29=7
.
%28Ax-B%29%2F%28C-B-3Bx%29=7 . Multiply each side by (C-B-3Bx)
.
Ax-B=7%28C-B-3Bx%29
.
Ax-B=7C-7B-21Bx
.
Ax%2B21Bx=7C-7B%2BB
.
x%28A%2B21B%29=7C-6B Divide each side by (A+21B)
.
x=%287C-6B%29%2F%28A%2B21B%29
