# How do you solve the equation -5t-2.2=-2.9?

Apr 7, 2018

$t = 1.4$

Here's how I did it:

#### Explanation:

We know that in an equation, both sides equal each other, so anything done on one side must also be done on the other.

$- 5 t - 2.2 = - 2.9$

The first thing we should do is add $2.2$ to both sides of the equation:
$- 5 t - 2.2 + \textcolor{red}{2.2} = - 2.9 + \textcolor{red}{2.2}$

$- 5 t = - 0.7$

Now we divide both sides by $- 5$ :
$- \frac{5}{\textcolor{red}{- 5}} t = - \frac{0.7}{\textcolor{red}{- 5}}$

$t = 1.4$

Hope this helps!
