4x/5+3/2=2x
multiply by 10
8x+15=20x
15=12x
15/12=x
5/4=x
1.25=x
Did you go back and try your 1.5 as x
Did it work? I don't think so.

%284%2F5%29x%2B%283%2F2%29=2x
%284%2F5%29x%2B%283%2F2%29=2x subtract 2x
%284%2F5%29x-2x%2B%283%2F2%29=0
%284%2F5%29x-%2810%2F5%29x%2B%283%2F2%29=0
-%286%2F5%29x%2B%283%2F2%29=0
-%286%2F5%29x=-%283%2F2%29multiply by -5%2F6
x=%2815%2F12%29
x=%285%2F4%29 x= 1 and 1/4 or 1.25
