    Subtract 6.4 from 42.5 so you can get 3.5n by itself.

    42.5-6.4=36.1

    then since you now have 3.5n by itself you are goin to divide 36.1 by 3.5

    36.1/3.5=10.31

    so n=10.31

    The first step to solving your equation would be to subtract 6.4 from both sides.

    3.5n+6.4=42.5

    Subtract 6.4

    3.5n=42.5
