Please can you help me solve x 


            3 + 3/x = 7 

The LCD = x, so multiply every term by x·

        x·3 + x·3/x = x·7

              1 
        x·3 + x·3/x = x·7
                  1

             3x + 3 = 7x

Add -3 to both sides

                 3x = 7x - 3

Add -7x to both sides

                -4x = -3

Divide both sides by -4

                  x = -3/(-4)

                  x = 3/4
