Which two integers would make each true? a) the sum of the integers is 23 less than the product b) the sum of the integers is 28 more than the product c) the sum of the integers is 73 more than the product

This problem could be set up algebraically or you could use trial and error.
a) 9 and 4 (9 + 4 = 13, 9 * 4 = 36 and 36 - 23 = 13)
I won't give you the rest of the answers, but the second and third ones have to add together to equal a negative number and multiply to equal a positive number. I hope this helps some.
