Answer 2

Solving the Equation 300 - x = 42

To solve the equation 300 - x = 42, we can use simple algebraic manipulation to isolate the variable x.

First, we'll subtract 42 from both sides of the equation: ``` 300 - x - 42 = 42 - 42 ``` This simplifies to: ``` 258 - x = 0 ```

Next, we'll isolate x by subtracting 258 from both sides: ``` 258 - x - 258 = 0 - 258 ``` This simplifies to: ``` -x = -258 ```

Finally, we'll multiply both sides by -1 to solve for x: ``` (-1) * (-x) = (-1) * (-258) ``` This simplifies to: ``` x = 258 ```

Solution:

The value of x that satisfies the equation 300 - x = 42 is x = 258.
