Respuesta :

-6.8 + 2.6 = -4.2
-4.2 + x = 9.7
x = 9.7 + 4.2
x = 13.9

Answer: 13.9

Step-by-step explanation:

Hey there!

So, when finding missing parts of an equation, in this case

-6.8 + 2.6 + x = 9.7

First add

-6.8 + 2.6 = -4.2

Then -4.2 + x = 9.7

To find x, add 4.2 and 9.7 and you get 13.9

Plug 13.9 into the equation for x to check if you are correct

-6.8 + 2.6 + 13.9 = 9.7

-6.8 + 16.5 = 9.7

9.7 = 9.7 ✔

Your solution checks

Hope this helps
