Question

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

Answer 1

`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.

`-5t-2.2=-2.9`

The first thing we should do is add `2.2` to both sides of the equation:
`-5t - 2.2 + color(red)(2.2) = -2.9 + color(red)(2.2)`

`-5t = -0.7`

Now we divide both sides by `-5` :
`-5/color(red)(-5)t = -0.7/color(red)(-5)`

`t = 1.4`

Hope this helps!
