Step 1.1.1

Apply the distributive property.

$4 x + 2 (2 x) + 2 \cdot - 3 = 4 (2 x - 2) + 2$

Step 1.1.2

Multiply $2$ by $2$ .

$4 x + 4 x + 2 \cdot - 3 = 4 (2 x - 2) + 2$

Step 1.1.3

Multiply $2$ by $- 3$ .

$4 x + 4 x - 6 = 4 (2 x - 2) + 2$

Step 1.2

Add $4 x$ and $4 x$ .

$8 x - 6 = 4 (2 x - 2) + 2$

Step 2.1.1

Apply the distributive property.

$8 x - 6 = 4 (2 x) + 4 \cdot - 2 + 2$

Step 2.1.2

Multiply $2$ by $4$ .

$8 x - 6 = 8 x + 4 \cdot - 2 + 2$

Step 2.1.3

Multiply $4$ by $- 2$ .

$8 x - 6 = 8 x - 8 + 2$

Step 2.2

Add $- 8$ and $2$ .

$8 x - 6 = 8 x - 6$

Step 3

Move all terms containing $x$ to the left side of the equation.
