The following equation is being multiplied by the LCD. Complete the multiplication to eliminate the denominators
x+2/3x - 1/x-2 = x-3/3x

(3x)(x-2) [x+2/3x - 1/x-2] = (3x)(x-2) [x-3/3x]

The resulting equation is

x+2-1 = x-3

3x(x+2)-(x-2) = x-3

(x-2)(x+2)-1 = (x-3)(x-2)

(x-2)(x+2)-3x=(x-2)(x-3)
