Answer 2

Step-by-step explanation:

2x + 3y = - 12 .....1st equation

x + 2y = - 1

x= - 2 - 2y ........2nd equation,

than substituting the valve of x in 1st eqn

so,

2( -2 - 2y) + 3y = -12

-4 - 4y + 3y = -12

-4 -y = -12

-y = -12 + 4

: y = 8

Now,

put valve of y in eqn

x = -2 - 2 x 8

x = -2 - 16

x = -18 answer
