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
