x=42

Answer 3

To solve the equation (120 - x) + 500 = 479 + 99, follow these steps:

1. First, simplify both sides of the equation:

   (120 - x) + 500 = 479 + 99

   120 - x + 500 = 578

2. Now, subtract 500 from both sides of the equation to isolate the term with 'x' on the left side:

   120 - x + 500 - 500 = 578 - 500

   120 - x = 78

3. Finally, solve for 'x' by subtracting 120 from both sides:

   120 - x - 120 = 78 - 120

   -x = -42

4. To isolate 'x', divide both sides by -1:

   -x / -1 = -42 / -1

   x = 42

So, the solution to the equation is x = 42.
