  • 8 x  + 2 - 16 < 5 x + 7x 

    Simplify: ( add / subtract numbers : 2 - 16 )

    - 8 x + 2 - 16

    - 8 x + 14

    Simplify 5x + 7x  = 12 x

    -8 x - 14 < 12 x

    add 14 to both sides:

    - 8 x - 14 + 14 < 12 x + 14

    -8 x < 12 x + 14

    Subtract 12 x from both sides:

    - 8 x - 12 x < 12 x + 14 - 12 x

    - 20 x < 14

    Multiply both sides by -1 ( reverse the inequality )

    (-1) (-20 x ) > ( -1 ) ( 14 )

    20 x > - 14

    Divide both sides by 20 :

    20 x / 20 > -14 / 20

    x > - 7 / 10

    hope this helps !.
