Answer:
Step-by-step explanation:
to solve this system of equations we will add them
x-3y=-12
2x+3y=3 now +3y-3y=0
3x=-12+3
3x=-9
x=-3
plug in the first equation
-3-3y=-12
-3y=-12+3
-3y=-9
y=3
You do the reverse and divide the 2 values to find out the last one
72/9 = 8
Do you get it?
The correct answer is #2: 6,2 9,3 12,4 because all of these answers equal 1/3
