#### Answer

There are no solutions for this system.

#### Work Step by Step

$x - y = 1$
$-2x + 2y = 5$
Express x in terms of y from the first equation.
$x = 1 + y$
Substitute x to solve for y in the second equation.
$-2*(1+y)+2y=5$
$-2y +2y -2 = 5$
$-2 = 5$
This shows us that there are no solutions for this system.
