  1. a) x+3,12=14,6-8,5
    x+3,12=6,1
    x=6,1-3,12
    x=2,98
    Vậy x=2,98
    b) x-5,14=(15,7+2,3)xx2
    x-5,14=18xx2
    x-5,14=36
    x=36+5,14
    x=41,14
    Vậy x=41,14
     

  2. x+3,12=14,6-8,5
    ->x+3,12=6,1
    ->x=6,1-3,12
    ->x=2,98
    Vậy x=2,98
    $\\$
    x-5,14=(15,7+2,3)xx2
    ->x-5,14=18xx2
    ->x-5,14=36
    ->x=36+5,14
    ->x=41,14
    Vậy x=41,14
