I have gotten to this point on my problem:

(x-4)/(x-2)=4

multiply both sides by (x-2):

x-4=4(x-2)

expand left side:

x-4=4x-8

add 8 to both sides:

x+4=4x

and here im stuck. Can i subtract an "x" from both sides to get an answer of 4/3? or do i have to subract 4 from both sides and divide by x?? im so confused
