Answer:

Step-by-step explanation:

3x+2y=11

2x+3y=4

a₁=3   ,   b₁=2    ,     c₁=11

a₂=2   ,   b₂=3   ,    c₂=4

    x           =          y           =        1        

b₁c₂-b₂c₁          c₁a₂-c₂a₁         a₁b₂-a₂b₁

     x          =          y          =          1      

2*4 - 3*11          11*2 - 4*3           3*3 - 2*2

 x        =         y         =         1        

8-33            22-12               9-4

 x   =   y   =  1

-25     10       5

 x   =  1

-25      5

x=-5

y  =   1

10       5

y=2

∴(x,y)=(-5,2)
