Question

x - y = -1
3x + 2y = 12

Answer 1

x =2
y=3 this is a correct answer

Answer 2

by the elimination method,
we multiply 2 to the 1st equation
then,
2x-2y=-2                                                               therefour,
3x+2y=12                                                                 x=-10
-------------                                                                  y=11
-x=10
therefour x=-10
then we subtitute x to the 1st equation,
10-y=-1=>-y=-11=>y=11
i think it will help u
