Final answer:
To solve the equation ys + yz = r for y, factor y out of the left side to get y(s + z), then divide both sides by (s + z) to find y = r / (s + z).
Step-by-step explanation:
The student has asked to solve the equation ys + yz = r for y. To isolate y, follow these steps:
- Factor y out of the left side of the equation, giving y(s + z).
- Divide both sides of the equation by (s + z) to solve for y. This results in y = r / (s + z).
Therefore, the solution for y is y = r / (s + z).
