Step 1.1.1

Subtract $y$ from both sides of the inequality.

$x + 2 y - y \leq 2 x$

Step 1.1.2

Subtract $y$ from $2 y$ .

$x + y \leq 2 x$

Step 1.2

Move all terms not containing $y$ to the right side of the inequality.

Step 1.2.1

Subtract $x$ from both sides of the inequality.

$y \leq 2 x - x$

Step 1.2.2

Subtract $x$ from $2 x$ .

$y \leq x$

Step 2

Subtract $2 x$ from both sides of the inequality.

$y \geq - 2 x$

Step 3

Find the intersection of $y \leq x$ and $y \geq - 2 x$ .

$- 2 x \leq y \leq x$
