Cross mulitplying we get;
3(x-2) = 2(x-1)
3x-6 = 2x-2
Rearranging we get:
3x-2x = 6-2
x = 4

Your LCD is 6 so multiply both sides by six:
3(x - 2) = 2(x - 1)
3x - 6 = 2x - 2
x = 4
You may check your solution:
(x - 2)/2 = (x - 1)/3
(4 - 2)/2 = (4 - 1)/3
2/2 = 3/3
1 = 1
so you have solve correctly.

(x-2)/2=(x-1)/3 <=>
<=> (x-2) . 1/2 = (x-1). 1/3
<=> (x/2) - (2/2) = (x/3) - 1/3
<=> (x/2) - (x/3) = -1/3 + 1
<=> (3x/6) - (2x/6) = - 1/3 + 1
<=> (x/6) = -1/3 + 3/3
<=> (x/6) = 2/3
<=> x = (2/3) . 6
<=> x = (6.2) / 3
<=> x = 4

cross multiply
3(x-2) = 2(x-1)
3x-6=2x-2
x=4

Just cross multiply.
3x - 6 = 2x - 2
x = 4

x-2/2=x-1/3
multiply each side by 6
3(x-2)=2(x-1)
3x-6=2x-2
3x-2x-6+6=2x-2x-2+6
x=4
