Answer:
x=34/5 y=6/5
Step-by-step explanation:
so first you need to isolate one variable in one equation
so lets use 3x-12y=6
3x=12y+6
x=4y+2
then, as the name implies, we substitute it into the second equation
3(4y+2)-7y=12
then we simplify
12y+6-7y=12
5y=6
y=6/5
then we plug it in to find x
3x-7(6/5)=12
3x-42/5=12
3x=102/5
x=34/5
check work
3(34/5)-12(6/5)=6
102/5-72/5=6
30/5=6
6=6
The answer it’s D again lol
