    Answer:

    no solution

    Step-by-step explanation:

    |x| + 7 < 4

    Subtract 7 from each side

    |x| + 7-7 < 4-7

    |x| < -3

    But an absolute value must be greater than or equal to zero

    There is no solution

    Answer: No solutions

    Let’s solve the inequality step-by-step

    |x|+7<4

    First subtract 7 from both sides

    |x|+7-7<4-7\\|x|<-3

    Now usually you’d solve absolute value, but absolute value cannot be less than 0 so there can’t be a solution.
