Answer:

Step-by-step explanation:
Given that Y is between X and Z;

Given;

Let us substitute the given equation into the equation above;

Let now proceed to solve the equation;
add 2 to both sides of the equation;

subtract 13m from both sides;

Then lastly divide both sides by 2;

Since we have the value of m, let now substitute into YZ to get its value;

Therefore, the value of m and YZ is;
