    1. x-2<3

    x<3+2

    x<5

    2. 2(x+1)<4

    2x+2<4

    2x<4-2

    2x<2

    x<2/2

    x<1

    3. 7x-9>9x+7

    7x>9x+7+9

    7x>9x+16

    7x-9x>16

    -2x>16

    x<16/(-2) (Since -1 will be put on the other side, so the inequality will be reverse)

    x<(-8)

    4. x+3>2

    x>2-3

    x>(-1)
