Combine like terms to create an equivalent expression.
3.4-2.8d+2.8d-1.33.4−2.8d+2.8d−1.3

Hey there!

Let's combine like terms!

First, let's write them together, like so:

-2.8d+2.8d-2.8d+2.8d-1.33+3.4-1.33

And now we can see that -2.8d and 2.8d cancel out:

-2.8d+2.8d-1.33+3.4-1.33

And they cancel out again:

-1.3+3.4-1.33

Now all we have to do is add the numbers together:

0.77

Hope it helps!
