ALG2!

posted by on .

-3K - 8 is less than or equal to 5k .....solve please

  • ALG2! - ,

    add 3 k to each side

    -3k-8>=5k
    -8>=8k
    divide each side by 8

    -1>=k or k<=-1

  • ALG2! - ,

    - 3 k - 8 < = 5 k Subtract 5 k to both sides

    - 3 k - 8 - 5 k < = 5 k - 5 k

    - 8 k - 8 < = 0 Add 8 to both sides

    - 8 k - 8 + 8 < = 0 + 8

    - 8 k < = 8 Divide both sides by - 8

    Remark :

    If you multiply or divide both sides of an inequality by a negative number, you must reverse the direction of the inequality sign.
