2 + 6y = 0
6y = - 2
y = - 2 / 6
y = - 1 / 3

3x + 6y = 0 x=2/3
3(2/3)+6y = 0
2+6y = 0
6y = -2
y= -1/3

Substitute x = 2/3 into the equation 3x + 6y = 0
3 (2/3) + 6y = 0
2 + 6y = 0
Subtract 2 from both sides
6y = -2
divide both sides by 6
y = -1/3

3x + 6y = 0 ; x=2/3
3(2/3)+6y=0
2+6y=0
6y= -2
y= -1/3

3 * 2/3 + 6y =0
2+6y = 0
6y = -2
y= -2/6
y= -1/3
by the way u should do it urself

3(2/3) +6y = 0;
2 + 6y = 0
6y = -2
y = -1/3
therefore, y = -1/3

since x=2/3, just compensate it's value in the first equation ... and try to get the value of y ...
