Solve for x:
c - 1
-------- + d = cd
x
c - 1
-------- + d = cd
x
c - 1
------- = cd - d {subtracted d from both sides}
x
c - 1 = x(cd - d) {multiplied both sides by x}
c - 1
---------- = x {divided both sides by cd - d}
cd - d
c -1
---------- = x {factored d out of bottom}
d(c - 1)
1
--- = x {cancelled c - 1 on top and bottom}
d
