Enter the equation: 3 less than 1/2 a number is - 71.

The answer would be 1/2N-3=-71 because if the awhile thing need to be - 71 then you first need to set it equal to - 71 and then if it needs to be a have of a number use N and the number and to find a half of something you times it by. 5 or 1/2 and then subtract 3 from that
