Answer:
s= -5
Step-by-step explanation:
-12=8+4s
We move all terms to the left:
-12-(8+4s)=0
We add all the numbers together, and all the variables
-(4s+8)-12=0
We get rid of parentheses
-4s-8-12=0
We add all the numbers together, and all the variables
-4s-20=0
We move all terms containing s to the left, all other terms to the right
-4s=20
s=20/-4
s=-5
