SOLUTION: Solve the system by addition or substitution.
3x + 6y = 0
x = 2/3 (this is a fraction)
The 6y = 0 and
x = 2/3 are supposed to be lined up under each other

Substituting the value 2/3 into the first equation, we have:
, which simplifies to:
.
Subracting 2 from both sides, we have:
.
Dividing through by 6:
Always check. So substitute x=2/3 and y=-1/3 back into the original equation:
. Check.

Solve the system by addition or substitution.
3x + 6y = 0
x = 2/3
------------
Substitute to solve for y:
3(2/3) + 6y = 0
2 + 6y = 0
y = -1/3
-------------
Solution: x = 2/3; y = -1/3
