I need help with this problem: |-4x| + |-5| < 1
I need help with this problem: |-4x| + |-5| < 1 Rewrite |-5| as 5 |-4x| + 5 < 1 Add -5 to both sides |-4x| < -4 There can be no solution because every absolute value is nonnegative, and no nonnegative number can be less than -4, since they are all greater than 0. So the solution set is Ø, the null or empty set. Edwin
