Solve for b r=(7+b)m

$r = (7 + b) m$

Step 1

Rewrite the equation as $(7 + b) m = r$ .

$(7 + b) m = r$

Step 2

Divide each term in $(7 + b) m = r$ by $m$ and simplify.

Divide each term in $(7 + b) m = r$ by $m$ .

$\frac{(7 + b) m}{m} = \frac{r}{m}$

Simplify the left side.

Cancel the common factor of $m$ .

Cancel the common factor.

$\frac{(7 + b) m}{m} = \frac{r}{m}$

Divide $7 + b$ by $1$ .

$7 + b = \frac{r}{m}$

Step 3

Subtract $7$ from both sides of the equation.

$b = \frac{r}{m} - 7$
