Can you use digits 1 to 9 to create 3 sums and answers by only using each digit once?
no you can't. the digits 1 - 9 summed together equal 45, an odd number. there is only 9 digits also meaning you need to use 3 in each equation. The digits in each equation must necessarily be an even number, with the end result that you are 1 digit short of being able to provide the necessary answer.
