Lets say that Autumn's current age is: [tex]\boxed{x}[/tex]
That means Jamal's age = [tex]\boxed{x+22}[/tex]
In 4 years:
Autumn's age is: [tex]\boxed{x+4}[/tex]
Jamal's age is: [tex]x+22+4=\boxed{x+26}[/tex]
(you add 4 because in 4 years, they will be four years older)
Now that we've worked out their ages in 4 years, we can form an equation, and solve. Because their ages now add up to be equal to 72:
[tex](x+4)+(x+26)=72[/tex]
[tex]2x+30=72[/tex]
[tex]2x=42[/tex]
[tex]\boxed{x=21}[/tex]
___________________________
So Autumns age is: 21 and
Jamal's age is: 21 + 22 = 43
___________________________________________
Autumn = 21 years old
Jamal = 43 years old
