Solve and check the following equations for x.

5%2F%28%28x%2B6%29%29 + 2%2F%28%28x%5E2%2B7x%2B6%29%29 = 3%2F%28%28x%2B1%29%29
:
5%2F%28%28x%2B6%29%29 + 2%2F%28%28x%2B1%29%28x%2B6%29%29 = 3%2F%28%28x%2B1%29%29: factored (x^2+7x+6)
:
Multiply thru by (x+6)(x+1) and you have:
5(x+1) + 2 = 3(x+6)
:
5x + 5 + 2 = 3x + 18
:
5x + 7 = 3x + 18
:
5x - 3x = 18 - 7
:
2x = 11
:
x = 11/2 = 5.5
:
I'll let you check it: substitute 5.5 for x in the original equation.
