The unknown number is going to be x, and we know that sum means the answer to an addition problem which means that x+6 will be multiplied by nine as the statement wants you to do. The statement also tells us that nine times the sum of a number and 6 is equal to 8. We have the first part of the problem solved all we need to do is set it equal to 8 which gives us the answer 9(x+6) = 8
