$9 c - (q - 2) = 6 c + 2 (c + 1)$

Step 1

Since $c$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$6 c + 2 (c + 1) = 9 c - (q - 2)$

Step 2

Simplify $6 c + 2 (c + 1)$ .

Step 2.1.1

Apply the distributive property.

$6 c + 2 c + 2 \cdot 1 = 9 c - (q - 2)$

Step 2.1.2

Multiply $2$ by $1$ .

$6 c + 2 c + 2 = 9 c - (q - 2)$

Step 2.2

Add $6 c$ and $2 c$ .

$8 c + 2 = 9 c - (q - 2)$
