Solve for j c=1/2jr

$c = \frac{1}{2} j r$

Step 1

Rewrite the equation as $\frac{1}{2} \cdot (j r) = c$ .

$\frac{1}{2} \cdot (j r) = c$

Step 2

Multiply both sides of the equation by $2$ .

$2 (\frac{1}{2} \cdot (j r)) = 2 c$

Step 3

Simplify the left side.

Simplify $2 (\frac{1}{2} \cdot (j r))$ .

Multiply $\frac{1}{2} (j r)$ .

Combine $j$ and $\frac{1}{2}$ .

$2 (\frac{j}{2} r) = 2 c$

Combine $\frac{j}{2}$ and $r$ .

$2 \frac{j r}{2} = 2 c$

Cancel the common factor of $2$ .

Cancel the common factor.

$2 \frac{j r}{2} = 2 c$

Rewrite the expression.

$j r = 2 c$

Step 4

Divide each term in $j r = 2 c$ by $r$ and simplify.

Divide each term in $j r = 2 c$ by $r$ .

$\frac{j r}{r} = \frac{2 c}{r}$

Simplify the left side.

Cancel the common factor of $r$ .

Cancel the common factor.

$\frac{j r}{r} = \frac{2 c}{r}$

Divide $j$ by $1$ .

$j = \frac{2 c}{r}$
