Answer:
There is no solution to this system.
Explanation:
To solve this problem solve the second equation for y.
2x + y = 9
y = -2x + 9
Now that we have the value of y, we can put that in for y in the first equation and solve for x.
3y = -6x + 4
3(-2x + 9) = -6x + 4
-6x + 27 = -6x + 4
27 = 4
Because this is a false statement, we know that this system has no solution.
