x=1x=1

Explanation:

Solving the rational equation is computed by finding same denominator for denominators in both sides of the equation

Then,
if color(red)(a/c=b/c then color(red)(a=c

Then common denominator is the L.C.M(2x-4,x-2)
color(blue)(2x-4=2(x-2)
then color(blue)(2x-4) is the common denominator

rArr(x-3)/(2x-4)=(color(blue)2x)/(color(blue)2(x-2))+(2xxcolor(blue)(2(x-2)))/color(blue)(2(x-2))

rArr(x-3)/(2x-4)=(2x+4(x-2))/(2x-4)

rArr(x-3)/(2x-4)=(2x+4x-8)/(2x-4)

rArr(x-3)/(2x-4)=(6x-8)/(2x-4)

Then
color(red)(x-3=6x-8)

rArrx-6x=3-8

rArr-5x=-5
rArrx=(-1)/(-1)

Therefore, x=1
