  2. subtract 43 from both sides
    9.65n=58-43+8.40n
    9.65n=15+8.40n
    subtract 8.40n from both sides
    9.65n-8.40n=15
    1.25n=15
    divide it by 1.25
    n=12
    go back to the equation and plug in
    12
    9.65(12)+43=8.40(12)+58
    158.8=158.8
    There are infinity many solutions to this problem
