    3x + 7 <_ 4x - 8

    Subtract 3x from both sides.

    3x - 3x = 0x

    4x - 3x = 1x (or just x)

    7 <_ x - 8

    Add 8 to both sides.

    7 + 8 = 15

    -8 + 8 = 0

    x _> 15 is the solution for the first inequality.

    Although A.) is the only one with x_>15, let's continue to ensure our answer.

    -2x + 3 _> 1

    Subtract 3 from both sides.

    3 - 3 = 0

    1 - 3 = - 2

    -2x _> - 2

    Divide both sides by - 2 to solve for x.

    -2x / - 2 = x

    -2 / - 2 = 1

    Remember to flip the inequality when dividing or multiplying by a negative.

    x <_ 1 is our other inequality.

    Our answers are:

    x_> 15 and x<_1
