# How do you solve 5u - 31\leq - 2( 5- 4u )?

Apr 11, 2018

-7 ≤ u

#### Explanation:

Expand on the right side so you get

$- 2 \times 5 = - 10 \text{ }$ and $\text{ } - 2 x - 4 u = 8 u$

This gives you

5u-31≤-10 + 8u

Next, you want to take away $5 u$ from both sides and add $10$ to both sides. This gives

-21≤3u

You can then divide both sides by $3$ to get $u$, so

-21/3 ≤ u

$- 7 \le u$
