Question

$$\frac{2r+5}{r+4}=1$$

Solve for r

$r=-1$

Steps for Solving Linear Equation

Variable $r$ cannot be equal to $-4$ since division by zero is not defined. Multiply both sides of the equation by $r+4$.

$$2r+5=r+4$$

Subtract $r$ from both sides.

$$2r+5-r=4$$

Combine $2r$ and $-r$ to get $r$.

$$r+5=4$$

Subtract $5$ from both sides.

$$r=4-5$$

Subtract $5$ from $4$ to get $-1$.

$$r=-1$$
