Answer:
x=0 , y=0
Step-by-step explanation:
2x +6y= 8 .....eqn 1
4x +12y= 16....eqn2
we multiply eqn 1 by 2.. because we want at least one variable to have the same coefficient so we can simply.
2x +6y =8... ×2
will give you 4x +12y = 16....eqn 3
so now we subtract eqn 2 from eqn 3
4x + 12y= 16
- 4x + 12y = 16
_____________
0 + 0 = 0
therefore x = 0 and y= 0
