I will assume you mean

(7/3)x + (1/3)x = 4x + 48/3 + (8/3)x

The LCD is 3, so multiply each term by that

7x + x = 12x + 48 + 8x
etc.

If your meant
7/(3x) + 1/(3x) = 4x + 48/3 + 8/(3x)
the the LCD is 3x and multiplying by that ...
7 + 1 = 12x^2 + 8
12x^2 = 0
x = 0
but then the original would be undefined, since we cannot divide by zero.
