Answer:
Peyton: 6 years old
Matt: 24 years old 
Justin: 9 years old
Step-by-step explanation:
P= Peyton   M= Matt   J= Justin
P=J-3
M=4P
J+P+M=39
4J-12=M  4J-12=39-J-P
5J-51=-P    P=J-3
5J-51=-J+3    J=9
P=9-3  P=6
M=4(6)  M=24
 
        
             
        
        
        
Answer:
A. x =2 
Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16
Distribute
Add the numbers
Add 8 to both sides of the equation
Simplify
Add 12x to both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify -------> x=2
