How do you solve 5.6= 8.8- 2u?

May 2, 2018

$u = - 1.6$

Explanation:

To solve this, we need to make our variable $u$ alone.

The first thing we do is subtract $\textcolor{b l u e}{8.8}$ from both sides of the equation:
$5.6 \quad \textcolor{b l u e}{- \quad 8.8} = 8.8 - 2 u \quad \textcolor{b l u e}{- \quad 8.8}$

$- 3.2 = - 2 u$

Divide both sides by $\textcolor{b l u e}{- 2}$:
$\frac{- 3.2}{\textcolor{b l u e}{- 2}} = \frac{- 2 u}{\textcolor{b l u e}{- 2}}$

$- 1.6 = u$

So the answer is $u = - 1.6$

Hope this helps!
