What is the value of s?

[tex]0.7(3s+4)-1.1s=7.9[/tex]

Enter the answer as a decimal in the box.

s =__

Respuesta :

s = 5.1

First distribute:

2.1s + 2.8 - 1.1s = 7.9

Then combine like terms:

s + 2.8 = 7.9

Subtract 2.8 from both sides:

s + 2.8 +(-2.8) = 7.9 +(-2.8)

And finally your answer:

s = 5.1
