Step 1: Given information:

Consider the equation,

$2 (x + 3) - 1 = - 7$

Step 2:

Use the Distributive property:

$2 x + 6 - 1 = - 7$

$2 x + 5 = - 7$

Step 3:

Add $(- 5)$ on both sides,

$2 x + 5 - 5 = - 7 - 5$

$2 x = - 12$

Step 4:

Divide by 2 on both sides,

$\frac{2 x}{2} = \frac{- 12}{2} x = - 6$
