The directions say to solve the rational equation and to find the excluded values and LCD.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

12%2Fx+%2B+3%2F4 = 3%2F2.

When you have a rational equation like this, multiply both sides by the common denominator to rid off denominators.

In this case multiply both sides by 4x. You will get

48 + 3x = 6x,

48 = 6x - 3x,

48 = 3x,

x = 48%2F3 = 16.

Please check yourself that the solution is correct.
