how would you explain how to do Inequalities? With negative numbers, and how to add and subtract ex: a+7<10+? how would that be solved .

  • algebra -

    You would isolate the variable to one side of the inequality.

    A+7<10
    A< 3

    Whenever A is less than 3 the inequality is true.

    If it were
    -A-8 < 10
    -A < 18
    At this point you would divide both sides by -1, when dividing by a negative with an inequality the inequality flips so the answer would like:

    A > 18
