Answer:
To make "r" the subject of the equation "d = r + 14," we need to isolate "r" on one side of the equation.
Here's how we can do it step by step:
1. Start with the equation: d = r + 14.
2. Subtract 14 from both sides of the equation to move the constant term to the other side: d - 14 = r.
3. Therefore, the equation becomes: r = d - 14.
By performing these steps, we have successfully made "r" the subject of the given equation "d = r + 14." Now, the equation "r = d - 14" represents the same relationship as the original equation, but with "r" as the subject.
