Substitution is the best method since the second equation has already been solved for y

Start with the given system

Plug in into the first equation. In other words, replace each with . Notice we've eliminated the variables. So we now have a simple equation with one unknown.

Distribute

Add 4 to both sides

Combine like terms on the right side

Divide both sides by 2 to isolate x

Divide

So our answer is and which also looks like (0,2)
