Robin's number is eight more than Sydney's. The sum of their numbers is 72. What are their numbers?

Answer 1

Let's assume Sydney's number is "x". Therefore, Robin's number is "x + 8".
Their sum is 72, so we can write the equation: x + (x + 8) = 72
By simplifying the equation, we have: 2x + 8 = 72
Subtracting 8 from both sides of the equation, we get: 2x = 64
Dividing both sides of the equation by 2, we get: x = 32
This means that Sydney's number is 32, and Robin's number is 32 + 8 = 40.
