Solve 2r+br=24

$$2 r + b r = 24$$

Solve for b

$$b=-2+\frac{24}{r}$$

$$r\neq 0$$

Steps for Solving Linear Equation

Subtract 2r from both sides.

$$br=24-2r$$

The equation is in standard form.

$$rb=24-2r$$

Divide both sides by r.

$$\frac{rb}{r}=\frac{24-2r}{r}$$

Dividing by r undoes the multiplication by r.

$$b=\frac{24-2r}{r}$$

Divide 24-2r by r.

$$b=-2+\frac{24}{r}$$

Solve for r

$$r=\frac{24}{b+2}$$

$$b\neq -2$$

Steps for Solving Linear Equation

Combine all terms containing r.

$$\left(2+b\right)r=24$$

The equation is in standard form.

$$\left(b+2\right)r=24$$

Divide both sides by 2+b.

$$\frac{\left(b+2\right)r}{b+2}=\frac{24}{b+2}$$

Dividing by 2+b undoes the multiplication by 2+b.

$$r=\frac{24}{b+2}$$
