Step 1.1.1

Apply the distributive property.

$- 4 (3 b) - 4 \cdot 4 + 13 b - 2 = 0$

Step 1.1.2

Multiply $3$ by $- 4$ .

$- 12 b - 4 \cdot 4 + 13 b - 2 = 0$

Step 1.1.3

Multiply $- 4$ by $4$ .

$- 12 b - 16 + 13 b - 2 = 0$

$- 12 b - 16 + 13 b - 2 = 0$

Step 1.2

Simplify by adding terms.

Step 1.2.1

Add $- 12 b$ and $13 b$ .

$b - 16 - 2 = 0$

Step 1.2.2

Subtract $2$ from $- 16$ .

$b - 18 = 0$

$b - 18 = 0$

$b - 18 = 0$

Step 2

Add $18$ to both sides of the equation.

$b = 18$
