2 = \frac{m}{2} - 7

$2 = \frac{m}{2} - 7$

Step 1

Rewrite the equation as

\frac{m}{2} - 7 = 2

$\frac{m}{2} - 7 = 2$ .

\frac{m}{2} - 7 = 2

$\frac{m}{2} - 7 = 2$

Step 2

Move all terms not containing

m

$m$ to the right side of the equation.

Step 2.1

Add

7

$7$ to both sides of the equation.

\frac{m}{2} = 2 + 7

$\frac{m}{2} = 2 + 7$

Step 2.2

Add

2

$2$ and

7

$7$ .

\frac{m}{2} = 9

$\frac{m}{2} = 9$

\frac{m}{2} = 9

$\frac{m}{2} = 9$

Step 3

Multiply both sides of the equation by

2

$2$ .

2 \frac{m}{2} = 2 \cdot 9

$2 \frac{m}{2} = 2 \cdot 9$

Step 4

Simplify both sides of the equation.

Step 4.1.1.1

Cancel the common factor.

2 \frac{m}{2} = 2 \cdot 9

$2 \frac{m}{2} = 2 \cdot 9$

Step 4.1.1.2

Rewrite the expression.

m = 2 \cdot 9

$m = 2 \cdot 9$

m = 2 \cdot 9

$m = 2 \cdot 9$

m = 2 \cdot 9

$m = 2 \cdot 9$

Step 4.2

Simplify the right side.

Step 4.2.1

Multiply

2

$2$ by

9

$9$ .

m = 18

$m = 18$

m = 18

$m = 18$

m = 18

$m = 18$

2 = \frac{m}{2} - 7

$2 = \frac{m}{2} - 7$
