Answer 2

Solving the Equation 624 - ... = 139,368

To solve the equation 624 - ... = 139,368, we can use simple algebra to find the missing number.

Let's denote the missing number as "x". The equation can be rewritten as:

624 - x = 139,368

To solve for x, we can isolate x on one side of the equation by performing the inverse operation of subtraction, which is addition.

Solution

By adding x to both sides of the equation, we get:

624 - x + x = 139,368 + x 624 = 139,368 + x

Now, to solve for x, we subtract 139,368 from both sides of the equation:

624 - 139,368 = 139,368 - 139,368 + x -138,744 = x

Answer

The missing number that needs to be inserted to make the equation 624 - ... = 139,368 true is -138,744.
