Step-by-step explanation:
3x/2-5y/3= -2
and,
x/3+y/2=13/6
x/3=13/6-y/2
x/3=26-6y/12
x/3=13-3y/6
x=3(13-3y)/6
x=13-3y/2
substitute in eqn (1)
3((13-3y)/2)-5y/3= -2
3(13-3y)/2-5y/3= -2
13-3y-10y/2= -2
13-13y/2= -2
13(1-y)= -4
1-y=-4/13
y=17/13
substitute in eqn (3)
x=(13-3(17/13))/2
x=169-51/26
x=118/26
x=59/13
