No. The only digit of 2 is ' 2 '. It adds up to 2.
9x8x7x6x5x4x3x2x1 or 9! which equals 362880 possible combinations if no digits are repeated
Let's assume there are 5 total digits, although that would have been handy information to include. All we can deduce from the available information is 4 of the digits. 318_2 There are ten possible digits for the 4th number, leaving 10 possible numbers.
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.

Answer is 411 Logic: You multiply the two numbers in LHS of the equation and reverse the result to form the first two digits of RHS and for the 3rd digit you subtract one from the 2nd number on the LHS of the equation.
