For substitution, we need to rearrange on of the equations so that we can substitute it in the other. Let’s pick eq2 and rewrite it as 2y = 16 – 4x. We see that eq1 also has 2y in it, so we can plug this new version of eq2 in there.

3x – (16-4x) = 12

Now solve for x.

7x=28, so x=4

Plug that into either equation to solve for y. You get y=0.
