$x - y = 11$ $2 x + y = 19$

Step 1

Reduce the system.

$y = - 11 + x, y = 19 - 2 x$

Step 2

Simplify the right side.

Step 2.1

Reorder $- 11$ and $x$ .

$y = x - 11$

$y = 19 - 2 x$

$y = x - 11$

$y = 19 - 2 x$

Step 3

Simplify the right side.

Step 3.1

Reorder $19$ and $- 2 x$ .

$y = - 2 x + 19$

$y = x - 11$

$y = - 2 x + 19$

$y = x - 11$
