Respuesta :

s + 2.8 = 6.59
s = ?

To solve for s use the inverse operation of addition, which is subtraction.

s + 2.8 = 6.59
6.59 - 2.8 = s
6.59 - 2.8 = 3.79
s = 3.79

Check:

s + 2.8 = 6.59
s = 3.79
3.79 + 2.8 = ?
3.79 + 2.8 = 6.59
Correct!

This proves: s = 3.79 ;)

In order to solve for the variable, isolate the variable.

s + 2.8 = 6.59
    - 2.8   -2.80 ( 2.8 is the same as 2.80 )

s = 3.79

Double check by plugging in the variable.

s + 2.8 = 6.59
3.79 + 2.8 = 6.59
6.59 = 6.59

Yes, it's correct!

Hope I helped!
