Answer:

x=0

y=6

Step-by-step explanation:

3y- 12x = 18

2y-8x= 12

rearrange the equation

2y-8x=12

add 8x to both sides

2y=8x+12

divide both sides by 2

y=4x+6

now substitute it into 3y-12x=18

3(4x+6)-12x=18

simplify

12x+18-12x=18

simplify

18=18

x=0

substitute to find y

2y-8(0)=12

2y=12

y=6

Recheck:

3(6)-12(0)=18

18=18

2(6)-8(0)=12

12=12
