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
