$36 - 2 a = 2 b$

Step 1

Subtract $36$ from both sides of the equation.

$- 2 a = 2 b - 36$

Step 2

Divide each term in $- 2 a = 2 b - 36$ by $- 2$ and simplify.

Step 2.1

Divide each term in $- 2 a = 2 b - 36$ by $- 2$ .

$\frac{- 2 a}{- 2} = \frac{2 b}{- 2} + \frac{- 36}{- 2}$

Step 2.2.1.1

Cancel the common factor.

$\frac{- 2 a}{- 2} = \frac{2 b}{- 2} + \frac{- 36}{- 2}$

Step 2.2.1.2

Divide $a$ by $1$ .

$a = \frac{2 b}{- 2} + \frac{- 36}{- 2}$

Step 2.3.1.1

Cancel the common factor of $2$ and $- 2$ .

Step 2.3.1.1.1

Factor $2$ out of $2 b$ .

$a = \frac{2 (b)}{- 2} + \frac{- 36}{- 2}$

Step 2.3.1.1.2

Move the negative one from the denominator of $\frac{b}{- 1}$ .

$a = - 1 \cdot b + \frac{- 36}{- 2}$

Step 2.3.1.2

Rewrite $- 1 \cdot b$ as $- b$ .

$a = - b + \frac{- 36}{- 2}$

Step 2.3.1.3

Divide $- 36$ by $- 2$ .

$a = - b + 18$
