Answer :

Answer:

[tex]s=2[/tex]

Step-by-step explanation:

You're asking to isolate the variable, not the value when we isolate the variable we will then find the value of the variable. In order to isolate the variable we will have to move the like terms to one side and then divide on both sides to find the value of the variable.

[tex]26-4s=9s[/tex]
Add 4s on both sides:
[tex]-4s+4s=0[/tex]
[tex]9s+4=13s[/tex]
[tex]26=13s[/tex]
Divide on both sides:
[tex]13s\div13s=s[/tex]
[tex]26\div13=2[/tex]
[tex]s=2[/tex]

Therefore the value of s is 2.

Hope this helps.
