show me what you have done so far.
1-1/x+2-2/x
writing down the equation by skipping the equal signs is not "showing some work"
1-1/x+2-2/x=3
1/2+2
1/2+2
1 - 1/x = 2 - 2/x
1 - 1/x = 2(1 - 1/x)
so, 1 - 1/x = 0
x = 1
so, 3 - 3/x = 3 - 3 = 0
1 - 1/x = 2(1 - 1/x)
so, 1 - 1/x = 0
x = 1
so, 3 - 3/x = 3 - 3 = 0
