# How do you solve for u in 8u=3u+35?

Apr 23, 2018

$u = 7$

#### Explanation:

$8 u = 3 u + 35$

Subtract $3 u$ from both sides

$8 u - 3 u = 5 u \mathmr{and} 3 u - 3 u = 0 \left(0 u\right)$

So

$5 u = 35$

Divide both sides by $5$

$\frac{5 u}{5} = u \setminus \text{as} \setminus \frac{5}{5} = 1 \mathmr{and} \frac{35}{5} = 7$

So

$u = 7$
