#### Answer

The answer is below.

#### Work Step by Step

a) In order to do this addition problem, it is first necessary to create common denominators. After creating a common denominator, the two fractions can be added like normal, and like terms can be combined. Finally, if possible, cancel out any factors that appear in the numerator and the denominator.
b) You should start this problem by subtracting by one of the fractions on both sides of the equations. After doing this, it is necessary to cross multiply. Finally, isolate x on one side of the equation in order to solve for x.
