    Answer:

    n<50

    Step-by-step explanation:

    7/2*5n + 14<49

    7n/2*5+14<49

    (7n)+(2*5)14/2*5 <49

    7n+10*14/2*5 <49

    7n+140/2*5 <49

    7n+140/10 <49

    7n+140 < 10*49

    7n+140 < 490

    (7n+140)+(-140)<490+(-140)

    7n+140-140<490-140

    7n<350

    7n/7 < 350/7

    n<2*5^2*7/7

    n<2*5^2

    n<2*25

    n<50
