  5. 56 = 1n +(2/5)n

    56 = (1+(2/5))n

    56 = (7/5)n

    n = (5/7)*56

    n= 40

  7. n + (2/5)n = 56

    The simple way is to convert 2/5 to a decimal. You can divide 2 by 5 on your calculator and obtain 0.4, then
    n + 0.4n = 56
    1n + 0.4n = 56
    1.4n = 56
    divide both sides by 1.4
    1.4n/1.4 = 56/1.4
    n = ??
