(x+5) .....3
-------- = ---
(x-6) ..... 4
Crossing:
4(x+5) = 3(x-6)
4x + 20 = 3x - 18
4x - 3x = -18 - 20
x = -38
Solution: {x belongs to R| x = -38}

did you see our last proof?
make them equal to each other

multiply both sides by 4/3
so that 4(x+5) = 3(x-6)

DOH ! - did you make this one up, too?
