First, distribute.

$(x - 3)/2 + 3/(2 - x) = 5x$

The LCD (least common denominator) is $(2)(2 - x)$

$((x - 3)(2 - x))/((2)(2 - x)) + ((3)(2))/((2 - x)(2)) = ((5x)(2)(2 - x))/((2)(2 - x))$

You can now eliminate the denominators since everything is equivalent,

$-x^2 - 3x + 2x - 6 + 6 = 20x - 10x^2$

$-x^2 - 21x + 10x^2 = 0$

$9x^2 - 21x = 0$

$3x(3x - 7) = 0$

$x = 0 and 7/3$

Hopefully this helps!
