Answer:
In 10 years from now Violet's age will be 27 years old
Step-by-step explanation:
Let
x ----> Ben's age
y ---> Violet's age
we know that
Ben is 5 years older than Violet
so
----> equation A
After eight years, Ben's age will be 1.2 times of Violet's age at that time.
so
----> equation B
substitute equation A in equation B
![(y+5+8)=1.2(y+8)](https://tex.z-dn.net/?f=%28y%2B5%2B8%29%3D1.2%28y%2B8%29)
solve for y
![y+13=1.2y+9.6\\1.2y-y=13-9.6\\0.2y=3.4\\y=17](https://tex.z-dn.net/?f=y%2B13%3D1.2y%2B9.6%5C%5C1.2y-y%3D13-9.6%5C%5C0.2y%3D3.4%5C%5Cy%3D17)
Find the value of x
![x=17+5=22](https://tex.z-dn.net/?f=x%3D17%2B5%3D22)
therefore
Ben's age is 22 years now
Violet's age is 17 years now
How old will Violet be 10 years from now?
Adds 10 years to Violet's age now
so
![17+10=27\ years](https://tex.z-dn.net/?f=17%2B10%3D27%5C%20years)
