I need it by step by step 12=6x +3y

4 = 2x + y

Step-by-step explanation:

To solve as a algebaic equation:

12= 6x + 3y

Divide by 3

4 = 2x + y

If you are doing this to put as a line, this is how you do it:

12 = 6x + 3y

Subtract 6x from both sides of the equation

-6x + 12 = 3y

Divide by 3

-2x + 4 = y

You know that the line would cross the x-coordinate at 4, so put a dot at (0,4)

Because it is -2x, that means for every one forward, you go 2 down. So your next point on the graph would be (1,2) then (2,0) then (3,-2) and so forth.

I hope that this helps! :)

step-by-step explanation: examine the two-step equation.
