# How do you solve 8/12=r/(r+1)?
Sep 15, 2016
Cross multiply, then solve as usual.
#### Explanation:
Cross multiply.
$8 \left(r + 1\right) = 12 r$
Expand the left-hand side.
$8 r + 8 = 12 r$
Subract $8 r$ from both sides.
$8 = 12 r - 8 r$
Simplify.
$8 = 4 r$
Divide both sides by $4$.
$\frac{8}{4} = r$

Dec 13, 2017
$x = 6$
Explanation:
This is a question having to do with basic algebra:
Step 1: Isolate the variable. Subtract $5$ from both sides:
$2 x + 5 - 5 = 17 - 5$
$2 x = 12$
Step 2: Solve. Divide both sides by $2$
$\frac{2 x}{2} = \frac{12}{2}$
