amistre64 · Answer

one way would be to solve each equation for x; and see if the y values give the same x solutions

I dont get what you mean @amistre64

amistre64 · Answer

the others methods like substitution and elimination work also ..

amistre64 · Answer

if the y values you have for answer choices is true; it will produce the same x value in each equation; just trial and error it

amistre64 · Answer

lets try that y=6

3x + 2y = 6
3x + 2(6) = 6
3x + 12 = 6
3x = -6
  x = -2

2x + 3y = −6 
2x + 3(6) = −6 
2x + 18 = -6
2x = -24
  x = -12

since -2 is not the same as -12; we know 6 is not a correct choice
