Final answer:
To solve rt - 2n = y for t, add 2n to both sides, then divide by r to isolate t, resulting in t = (y + 2n) / r.
Step-by-step explanation:
To solve the equation rt - 2n = y for the variable t, follow these steps:
- Start with the given equation: rt - 2n = y.
- Add 2n to both sides of the equation to isolate the term with t: rt = y + 2n.
- Divide both sides by r to solve for t: t = (y + 2n) / r.
The variable t is now isolated, and the equation can be used to find its value when y, n, and r are known.
