Answer:
consider this as two eqns,
1st multiply both eqn by 10.
so,
4x-15y=65----> eqn 3
3x+2y=9-------eqn 4
multiply eqn 3 with 3
12x-45y= 195
multiply eqn 4 with 4
12x+8y=36
Solve eqn 3 and 4 now,
12x-45y= 195
12x+8y=36
by subtracting,
-53y=159
y=3
subtitute y=3 value in eqn 3 and find x value.
4x-15(3)=65
4x-45=65
x=27.5
hope it helps
