Answer 3

To solve the equation 900 - x = 250 + 140, we can follow these steps:

1. Combine like terms on both sides of the equation: 900 - x = 390

2. To isolate x, subtract 900 from both sides of the equation: 900 - x - 900 = 390 - 900

• x = -510

3. Multiply both sides of the equation by -1 to solve for x: (-1) * (-x) = (-1) * (-510) x = 510

Therefore, the solution to the equation 900 - x = 250 + 140 is x = 510.
