Step 1.2.1

Move the leading negative in $- \frac{2}{5}$ into the numerator.

$\frac{- 2}{5} \cdot 5 - \frac{2}{5} (- 10 e) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.2.2

Cancel the common factor.

$\frac{- 2}{5} \cdot 5 - \frac{2}{5} (- 10 e) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.2.3

Rewrite the expression.

$- 2 - \frac{2}{5} (- 10 e) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.3

Cancel the common factor of $5$ .

Step 1.3.1

Move the leading negative in $- \frac{2}{5}$ into the numerator.

$- 2 + \frac{- 2}{5} (- 10 e) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.3.2

Factor $5$ out of $- 10 e$ .

$- 2 + \frac{- 2}{5} (5 (- 2 e)) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.3.3

Cancel the common factor.

$- 2 + \frac{- 2}{5} (5 (- 2 e)) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.3.4

Rewrite the expression.

$- 2 - 2 (- 2 e) = e + \frac{1}{3} \cdot (6 e - 12)$

Step 1.4

Multiply $- 2$ by $- 2$ .

$- 2 + 4 e = e + \frac{1}{3} \cdot (6 e - 12)$

Step 2.2.1

Factor $3$ out of $6 e$ .

$- 2 + 4 e = e + \frac{1}{3} (3 (2 e)) + \frac{1}{3} \cdot - 12$

Step 2.2.2

Cancel the common factor.

$- 2 + 4 e = e + \frac{1}{3} (3 (2 e)) + \frac{1}{3} \cdot - 12$

Step 2.2.3

Rewrite the expression.

$- 2 + 4 e = e + 2 e + \frac{1}{3} \cdot - 12$

Step 2.3

Step 2.3.1

Factor $3$ out of $- 12$ .

$- 2 + 4 e = e + 2 e + \frac{1}{3} \cdot (3 (- 4))$

Step 2.3.2

Cancel the common factor.

$- 2 + 4 e = e + 2 e + \frac{1}{3} \cdot (3 \cdot - 4)$

Step 2.3.3

Rewrite the expression.

$- 2 + 4 e = e + 2 e - 4$

Step 3

Add $e$ and $2 e$ .

$- 2 + 4 e = 3 e - 4$
