Answer 2

@tommylee21 try it fist.......

Answer 3

multiply the first equation by 2 and the second equation by -3
then add both equation

Answer 4

so y = -3 as i added them both and they where 0 (3*2=6 2*-3 =-6 ) is that correct

Answer 5

2 (3x+2y=6) then you have 6x+4y = 12
-3(2x+3y=-6) then you have -6x-9y = 18
---------------
now subtract

Answer 6

I meant add

Answer 7

-6
