a. n - 3.4 = 2312.2
Show Work: 2312.2
+ 3.4
----------
n = 2315.6
b. 1x = 5.12
Show Work: 5.12 divided by 1 would equal to 5.12 (Note: Anything times or divided by 1 would give you the same factor that you multiplied.)
x = 5.12
c. m + 2 = 7.8
Show Work: 7.8
- 2
-------
m = 7.6
d. 1.2 d = 6
Show Work: 1.2 divided by 6 would equal to 5.
d = 5
If you don't believe, check with an calculator, but glad to help! ^^
