Answer: Arun is now 20, Shree is 10 years old
Step-by-step explanation:
In the system of equations Arun's age is a. Shree is s
a = 2s .(current age equation) Subtract 5 from each for five years ago,
a-5 = 3(s-5) . Substitute 2s for a in the second equation
2s -5 = 3(s-5) distribute and reorganize
2s-5 = 3s -15 . 15 - 5 = 3s - 2s
10 = s . Substitute into the first equation to find a
a = 2(10)
a = 20
5 years ago Shree was 5 and Arun was 15
The answer is no. the first equation is not right
I believe the answer is 28.27, or 28.3
