Answer 3

To solve the equation 640/(25-x) = 40, we can follow these steps:

1. Start by multiplying both sides of the equation by (25-x) to eliminate the denominator: 640 = 40(25-x)

2. Distribute the 40 on the right side of the equation: 640 = 1000 - 40x

3. Move the constant term to the left side and the variable term to the right side: 40x = 1000 - 640

4. Simplify the right side: 40x = 360

5. Divide both sides of the equation by 40 to solve for x: x = 360/40

6. Calculate the division: x = 9

Therefore, the solution to the equation is x = 9.
