Answer:
0
Because -2/3x-1=2-2/3x
-2/3x+2/3x=2+1
0=3
and that's wrong, so there is no solution.
ANSWER
A. 0
EXPLANATION
The first equation is
2x + 3y = 6
The second equation is
y=-2/3x-1
Let us rewrite the first equation in slope-intercept form.
3y =-2x+ 6
[tex]y = - \frac{2}{3} x + 2[/tex]
We can see that both equations has the same slope,
[tex] m = - \frac{2}{3} [/tex]
but different y-intercepts.
This implies that the two lines do not intersect because they are parallel.
Therefore the system has no solution.
