I'm going to put in parentheses where I think they belong.
5 - (2 / (x - 6)) = 10 - (2x / (x-6))
Multiply both sides of the equation by (x - 6)
5(x - 6) - 2 = 10(x - 6) - 2x...........Multiplying we get:
5x - 30 - 2 = 10x - 60 - 2x
Group the x terms to the left hand side of the equation and the constants to the right hand side of the equation.
5x - 10x + 2x = 30 + 2 - 60
7x - 10x = 32 - 60
-3x = -28...........Multiply both sides of the equation by (-1)
3x = 28
x = 28/3 = 9.333333333.... <<<<<
If the parentheses are in the right places then this is the right answer. I'll bet my PhD in Mathematics on it.
