Step 1.1

Add

5

$5$ to both sides of the equation.

2 s = 7 + 5

$2 s = 7 + 5$

Step 1.2

Add

7

$7$ and

5

$5$ .

2 s = 12

$2 s = 12$

2 s = 12

$2 s = 12$

Step 2

Divide each term in

2 s = 12

$2 s = 12$ by

2

$2$ and simplify.

Step 2.1

Divide each term in

2 s = 12

$2 s = 12$ by

2

$2$ .

\frac{2 s}{2} = \frac{12}{2}

$\frac{2 s}{2} = \frac{12}{2}$

Step 2.2.1.1

Cancel the common factor.

$\frac{2 s}{2} = \frac{12}{2}$

Step 2.2.1.2

Divide

$s$ by

$1$ .

$s = \frac{12}{2}$

$s = \frac{12}{2}$

$s = \frac{12}{2}$
