Răspuns :
X : 3 + ( 123 x 3 - 54 x 4 ) = 357
x:3+(369-216)=357
x:3+153=357
x:3=357-153=204
x=204*3=612
x=612
x:3+(369-216)=357
x:3+153=357
x:3=357-153=204
x=204*3=612
x=612
Trebuie sa aflam x?
Legenda: * = ori / inmultit
X : 3 + (123 * 3 - 54 * 4) = 357
x: 3 + (369 - 216) = 357
x:3 + 153 = 356
x:3 = 356 - 153
x:3 = 203
x= 203 x 3
x= 609
