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
