# How do you find the point of intersection for x-y=3 and x-2y=3?

Jun 27, 2015

Ifound:
$x = 3$
$y = 0$

#### Explanation:

You can solve the System formed by the two equations trying to find values of $x$ and $y$ that simultaneously satisfy the two equations.
Isolate $x$ from the first equation:
$x = 3 + y$ substitute for $x$ into the second equation:
$\left(3 + y\right) - 2 y = 3$
$3 + y - 2 y = 3$
So: $y = 0$
Substitute back into the first equation:
$x = 3 + 0 = 3$
