Question

Given the equation Z = b (I-W), solve for W.

A) W = I - Z/b
B) W = I + Z/b
C) W = I - Z*b
D) W = I + Z*b

Answer 1

To solve the equation Z = b (I - W) for W, divide both sides by b, subtract I from both sides, and then multiply by -1, resulting in the solution W = I - Z/b (option A).

Step-by-step explanation:

To solve the equation Z = b (I - W) for W, follow these steps:

1. Divide both sides of the equation by b to isolate the term (I - W): Z/b = I - W.
2. To solve for W, get W on one side of the equation by subtracting I from both sides: (Z/b) - I = -W.
3. Finally, multiply both sides by -1 to get W by itself: W = I - (Z/b).

The correct answer is W = I - Z/b (option A).
