Answer:
x = -9/5
y = 16/5
Step-by-step explanation:
-3x-2y=-1            first you need to multiply the numerator by 3 so when adding
4x+6y=12           the y's cancel and you get a single variable
3(-3x-2y=-1)     —>  -9x - 6y = -3     then you add the like terms
  4x+6y=12      —>   4x + 6y = 12
(-9x+4x) + (6y - 6y) = (-3 + 12)
-5x = 9  then you divide by -5
x = -9/5
then you plug this in to either equation
4(-9/5) + 6y = 12
-36/5 + 6y = 12   then you add 36/5 to both sides
6y = 96/5  then you divide by 6
y = 16/5
