Step 1.2.2

Factor $2$ out of $2 x$ .

$3 + \frac{- 1}{2} (2 (x)) - \frac{1}{2} (- 4 y) - (x + y)$

Step 1.2.3

Cancel the common factor.

$3 + \frac{- 1}{2} (2 x) - \frac{1}{2} (- 4 y) - (x + y)$

Step 1.2.4

Rewrite the expression.

$3 - 1 x - \frac{1}{2} (- 4 y) - (x + y)$

Step 1.3

Step 1.3.2

Factor $2$ out of $- 4 y$ .

$3 - 1 x + \frac{- 1}{2} (2 (- 2 y)) - (x + y)$

Step 1.3.3

Cancel the common factor.

$3 - 1 x + \frac{- 1}{2} (2 (- 2 y)) - (x + y)$

Step 1.3.4

Rewrite the expression.

$3 - 1 x - 1 (- 2 y) - (x + y)$

Step 1.4
