anonymous · Answer

Multiply the first equation by 2 and the second -3 and ad them
6x + 4 y =26
-6x- 9y =-36
Add them
-5y =-10 , y=2
replace in the first equation and find x.

3x+2y=13    multiply by -2
2x+3y=12     -------      3

-6x-4y=-26
  6x+9y=36
-------------- assum 
  0    5y=10
         y=10/5 =2
y=2

2x+3*2=12
2x=12-6
2x=6
x=6/2
x=3

x=3
y=2
