7. Solve for x and check.
This is a rational equation, so we run through the steps for solving rational equations. First clear denominators. In this case the smallest common denominator is (x - 1)(x + 5). When we multiply both sides by (x - 1)(x + 5)
which amounts to cross multiplying
Transpose known terms to one side and unknown terms to the other
Divide both sides by the coefficient of the unknown.
Copy down the original equation
except that wherever you see an x, copy down the solution, in parentheses.
This gives us compound fractions. We simplify both of them. First do the additions and subtractions on both of the bottoms. For this we will need common denominators. Multiply and divide the number terms in the bottoms by 5.
Now that we have common denominators we can add and subtract on the bottoms.
We are now ready to invert and multiply.
