Answer:
[tex]s=5.1[/tex]
Step-by-step explanation:
We have been given an equation [tex]0.7(3s+4)-1.1s=7.9[/tex]. We are supposed to solve the given equation.
Using distributive property [tex]a(b+c)=ab+ac[/tex], we will get:
[tex]0.7(3s)+0.7(4)-1.1s=7.9[/tex]
[tex]2.1s+2.8-1.1s=7.9[/tex]
[tex]2.1s-1.1s+2.8=7.9[/tex]
[tex]1.0s+2.8=7.9[/tex]
[tex]s+2.8-2.8=7.9-2.8[/tex]
[tex]s=5.1[/tex]
Therefore, the solution for the given equation is [tex]s=5.1[/tex].
