Answer 3

To solve the equation 321 - x = 450, you need to isolate the variable x on one side of the equation.

1. Start by subtracting 321 from both sides:

   321 - x - 321 = 450 - 321

Simplifying the left-hand side gives:

-x = 129 -or- x = -129 

2. To check your answer, substitute x = -129 back into the original equation:

321 - (-129) = 450 

Simplifying the left-hand side gives:

321 + 129 = 450 

And the equation is true, which confirms that x = -129 is the solution to the equation 321 - x = 450.
