Final answer:
To make y the subject of the equation P = (1/6)cy - u, add u to both sides of the equation and then multiply both sides by (6/c). The equation that makes y the subject is y = (6/c)(P + u).
Step-by-step explanation:
To make y the subject of the equation, we need to isolate it on one side of the equation. Here's how:
Step 1: Start with the equation P = (1/6)cy - u
Step 2: Add u to both sides of the equation to move it to the other side: P + u = (1/6)cy
Step 3: Multiply both sides of the equation by 6/c to get rid of the fraction: (6/c)(P + u) = y
So, the equation that makes y the subject is y = (6/c)(P + u).
