Step 1.1

Add

2

$2$ to both sides of the equation.

2 j = 2 + 2

$2 j = 2 + 2$

Step 1.2

Add

2

$2$ and

2

$2$ .

2 j = 4

$2 j = 4$

2 j = 4

$2 j = 4$

Step 2

Divide each term in

2 j = 4

$2 j = 4$ by

2

$2$ and simplify.

Step 2.1

Divide each term in

2 j = 4

$2 j = 4$ by

2

$2$ .

\frac{2 j}{2} = \frac{4}{2}

$\frac{2 j}{2} = \frac{4}{2}$

Step 2.2.1.1

Cancel the common factor.

$\frac{2 j}{2} = \frac{4}{2}$

Step 2.2.1.2

Divide

$j$ by

$1$ .

$j = \frac{4}{2}$

$j = \frac{4}{2}$

$j = \frac{4}{2}$

Step 2.3

Simplify the right side.
