    Lời giải và giải thích chi tiết:
    $\text{(x+73):5=20+7,5×4}$
    $\text{(x+73):5=50}$
    $\text{x+73=50:5}$
    $\text{x+73=10}$
    $\text{x         =10-73}$
    $\text{x          =-63}$
    ___________________
    $\text{17,58×43+57×17,58}$
    =$\text{17,58x(43+57)}$
    =$\text{17,58×100}$
    =$\text{1758}$
    ____________________________
    $\dfrac{3}{8}$$\text{x}$=$\text{118}$
                            $\text{x}$=$\text{118}$:$\dfrac{3}{8}$
                            $\text{x}$= $\dfrac{944}{3}$
                            
                            

  2. (x + 73) : 5 = 20 + 7,5 . 4
    (x + 73) : 5 = 20 + 30
    (x + 73)  : 5 = 50
    x + 73 = 250
    x = 250 – 73
    x = 177
    —————–
    17,58 . 43 + 57 . 17,58
    = 17,58 . (43 + 57)
    = 17,58 . 100
    = 1758
    —————–
    3/8x = 118
    x = 118 : 3/8
    x = 314,66
