Solve for x (x+12)12=(4+8)8

$(x + 12) \cdot 12 = (4 + 8) \cdot 8$

Step 1

Simplify.

Add $4$ and $8$ .

$(x + 12) \cdot 12 = 12 \cdot 8$

Multiply $12$ by $8$ .

$(x + 12) \cdot 12 = 96$

Step 2

Divide each term in $((x + 12) \cdot 12) = 96$ by $12$ and simplify.

Divide each term in $((x + 12) \cdot 12) = 96$ by $12$ .

$\frac{((x + 12) \cdot 12)}{12} = \frac{96}{12}$

Simplify the left side.

Cancel the common factor of $12$ .

Cancel the common factor.

$\frac{(x + 12) \cdot 12}{12} = \frac{96}{12}$

Divide $x + 12$ by $1$ .

$x + 12 = \frac{96}{12}$

Simplify the right side.

Divide $96$ by $12$ .

$x + 12 = 8$

Step 3

Move all terms not containing $x$ to the right side of the equation.

Subtract $12$ from both sides of the equation.

$x = 8 - 12$

Subtract $12$ from $8$ .

$x = - 4$

Solve for x (x+12)*12=(4+8)*8
