318) How to get this one?

2x = 3y-5 and y ≠ 3, then (x-2) / (y-3) =?

the answer to this is 3 / 2. How is this possible to get??

2x=3y-5
=> y=2x/3 +5/3
=>y-3=(2x+5)/3 -3=(2x-4)/3
=>y-3=2(x-2)/3
=>(x-2)/(y-3)=3/2

2x = 3y - 5

subtract 4 frm both sides

2x-4=3y-5-4

2x-4=3y-9

2(x-4) = 3 (y-3)

(x-4)/(y-3) = 3/2
