I am solving inequalities then graphing my solution. in a problem such as

-2(c-1)<-22

how do i solve this? and also how do i know the greater then less then sign is going the right way?

  • Math -

    -2(c-1)<-22
    first divide both sides by negative 2 !! BUT !! remember that when you multiply (or divide) both sides of an inequality by a negative number you reverse the direction of the arrow.
    so
    c-1 > 11
    c > 12

    check
    try c = 13
    -2(12) < -22 ?
    -24 < -22 right, good
