2x-3y=-5 let write the formula
slope(m)=a/b
=2/-3
(m)=-2/3
a+3y=6
(m)=a/3
now we equal the answers
a/3=-2/3
a=-2 .
so the valus of a is -2.

Ques is very simple .
first point is that " If two lines are parellel to each other then the ratio of coefficient of x and y shoud be equal ."
Means ,
2x-3y=-5
-2x+3y=5.....(I)
ax+3y=6...(II)
so, -2/a = 3/3
a=(-2)
Hope you will get it .
All the best .
