What’s the answer to 6x + 3y =

Alex73 [517]

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.

$?=12\\$
