Lets say that Autumn's current age is:
![\boxed{x}](https://img.qammunity.org/2020/formulas/mathematics/high-school/r8iis2wdlfvy5e94j7lhsmg07jixrwbdz1.png)
That means Jamal's age =
![\boxed{x+22}](https://img.qammunity.org/2020/formulas/mathematics/high-school/sky2g0alhh8gb990k261djtjjokl861so0.png)
In 4 years:
Autumn's age is:
![\boxed{x+4}](https://img.qammunity.org/2020/formulas/mathematics/high-school/6ortz8ng5fjf7u1k2t6uucwlmnet4cmrnz.png)
Jamal's age is:
![x+22+4=\boxed{x+26}](https://img.qammunity.org/2020/formulas/mathematics/high-school/3cn1h7tw0b21kxzo1hemlexy1rrhv2qm9q.png)
(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:
![(x+4)+(x+26)=72](https://img.qammunity.org/2020/formulas/mathematics/high-school/58c0wqtmupjrnvtfjks65o6j2xeyy1ki9g.png)
![2x+30=72](https://img.qammunity.org/2020/formulas/mathematics/high-school/tolvm7yx4kvdw70s39j81r0by5y8voktur.png)
![2x=42](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9hf8sziknktjuvcc2a1z0zwltcp9vgrvop.png)
![\boxed{x=21}](https://img.qammunity.org/2020/formulas/mathematics/high-school/klug87zrq3lu3lcze7xg33jxfdypao5clh.png)
___________________________
So Autumns age is: 21 and
Jamal's age is: 21 + 22 = 43
___________________________________________
Answer:
