# How do you solve the simultaneous equations 3x=2+2y and x=(2+2y)/3?

Jul 23, 2015

You have the same 2 equations. These are two lines superimposed so they have $\infty$ common solutions.

#### Explanation:

You actually have the same equations but written in different ways.
You can substitute the second equation into the first for $x$ to see that:
$\cancel{3} \textcolor{red}{\frac{2 + 2 y}{\cancel{3}}} = 2 + 2 y$
Basically you have the same 2 lines superimposed one on the other.
