solve the compound inequality write the solution in interval notation
2u+4>-6 and 3u-6> -3 =

  • algebra -

    Solve each one individually:

    2u >-2
    u > -1

    3u > 3
    u >1

    Draw a number line and put an open circle or a ( at -1 and 1

    from -1 you will draw an arrow to the right on the number line

    from 1 you will draw an arrow to the right on the number line.

    AND means your answer is where the arrows overlap.

    The overlap should start at 1 and to to infinity.
    The final answer is x>1
