s = 1
Step-by-step explanation:
I moved all terms to the left:
2(8s-1)-(14s)=0
I added all the numbers together, and all the variables
-14s+2(8s-1)=0
I multiplied parentheses
-14s+16s-2=0
I added all the numbers together, and all the variables
2s-2=0
I moved all terms containing s to the left, all other terms to the right
2s=2
s=2/2
s=1
