5/(x+6)+ 2/(x^2+7x+6)= 3/(x+1) Rewrite x^2 +7x +1 as (x+6)(x+1) Multiply both sides of the equation by that expression. You get 5(x+1) + 2 = 3(x+6) Multiply out the parentheses and combine similar terms. You will be left with a simple linear equation for x.

x/(x-2)- (x+1)/x= 8/(x^2-2x) notice that x^2 - 2x factors to x(x-2), which are found as the denominators of the first two fractions. Multiply each term by x(x-2), the rest is easy.
