Answer:
no solution
Explanation:
Try getting a variable by itself, (I'm going to do so with 2x)
In order to do that I need to subtract 3y from both sides
The equation should now be
2x= -3y+4
Now divide by 2 to get x by itself
x= -3/2y+2
You can now plug x into 4x+6y=9
4(-3/2y+2)+6y=9
Distribute 4
-6y+8+6y=9
y cancels out and you're left with 8=9, which is untrue, so the answer is no solution
