Answer:

The last answer; 12.

Step-by-step explanation:

In order to solve this, use substitution. Since it gives you an equation for y, substitute that equation in the other formula as y. This will give you:

6x+3(-2x+4)=?

Then simplify:

6x-6x+12=?

Since 6x - 6x cancels out, you are left with 12.

?=12\\
