Am o intebere am facut un exercitiu si nu stiu daca e corect :
[(124+150-x):6]:31-2=0
(274-x:6):31-2=0
274-x*1 supra 6*1 supra 31-2=0
274-x*1 supra 186 -2=0
274-x supra 186-2=0 274 2 si zero au 186X3
50564-x supra 186- 372=0
50592-x=0
___^>___ supra 186
= 276
cum se face daca e grezit ?
VA ROG AJUTATIMA URGENT

[(124+150-x):6]:31-2=0
Rezolvare:
[(274 - x) : 6]:31 = 2
[(274 - x) : 6]= 2 * 31
(274 - x) : 6 = 62
(274 - x) = 62 * 6
274 - x = 372
x = 274 - 372
x = -98

PROBA:
[(124 + 150 + 98 ) : 6] : 31 - 2 = [372 : 6] : 31 -2 = 62 : 31 -2 = 2 - 2 = 0
