Find two whole numbers whose sum is 166 and difference is 32?
Let x be one of the numbers. Then the other number is 166 - x. Given that their difference is 32, we can set up the equation x - (166 - x) = 32 and solve for x. This yields x = 99 and 166 - x = 67. So, the two whole numbers are 99 and 67.
