Tyler thinks that the relationship between the ages of the children in Family B can be described with 2m – 2y = 10, where m is the age of the middle child and y the age of the youngest. Explain why Tyler is right.

m - y = 5 is equivalent to 2m - 2y = 10

Step-by-step explanation:

Given

m = age of middle child

y = age of youngest child

Explain why Tyler is correct

From the question, we understand that m is 5 greater than y

This can be represented as

m = 5 + y

To explain why Tyler is correct, we simply solve the above expression.

First, subtract y from both sides

m - y = 5

Multiply both sides by 2

2 * (m - y) = 2 * 5

2m - 2y = 10

This implies that m - y = 5 is equivalent to 2m - 2y = 10

And that means, Tyler conclusion is correct

the infinity sign
