Original equation:
Step 1: Put all of the factors under '1',and find an LCD

We're going to need to find a common LCD (least common denominator) in order to be able to subtract the fractions. The number that both factors go into is '7', so multiply '7' to the numerator and denominator of

You'll get:
Step 2: Combine like terms on the right side of the equation

Step 3: Subtract to both sides in order to avoid having to deal with negatives

Step 4: Find a new LCD... in this case it is , so the new LCD is Multiply both the numerator and denominator of both equations by factors that will make them equal 21

Step 5: Simplify

Step 6: Multiply the by its inverse(opposite) in order to cancel it out and get the 'x' by itself

Step 7: Simplify

The answer is or
