    Answer:

    x =  - 23

    Step-by-step explanation:

     \frac{20 - (40 + x)}{12}  \times 10 = 32.5 - 30 = 2.5

     =  >  \frac{20 - (40 + x)}{12}  = 0.25

     =  >  \frac{20 - (40 + x)}{12}  =  \frac{1}{4}

     =  > 20 - (40 + x) =  \frac{12}{4}  = 3

     =  > 40 + x = 20 - 3 = 17

     =  > x = 17 - 40 =  - 23
