You can make up any numbers for the first two blanks, then choose the number that is 5 less than what you get when you multiply the first two numbers you chose. Example; Choose 8 for the first blank and 13 for the second blank 8 × 13 - ___ = 5 Multiply 8 by 13 and get 104. Subtract 5, 104-5 = 99 So 99 goes in the remaining blank: 8 × 13 - 99 = 5 Edwin
We have numbers 1 - 3, as:
The equation then becomes:
As with any equation, substitute any 2 values for any 2 variables, and you can find the 3rd variable.
