-q/7 (greater than or equal to sign) -1
How do I do this step by step I am very confused. Please help.

  • Math -

    -q/7 >= -1
    -q >= -7
    q <= 7

    remember to change direction when multiplying/dividing by negative values. It's just a shortcut for the required addition and subtraction:

    -q >= -7
    add q:
    0 >= -q+q
    add 7:
    7 >= q

    The result is the same.

  • Math -

    -q/7 ≥ -1

    Multiply both sides by 7

    -q ≥ -7

    q ≥ 7

  • Math -

    I think I somewhat understand this with the way you explained this. This is all new to me.

    Thank you for your help. :)
