Question

{105-[25:(45:x)+72:12]:47}+684:6=116

Answer 1

Răspuns:

x=8703

Explicație pas cu pas:

{105-[25:(45:x)+72:12]:47}+114=116

105-(5x:9+6):47=116-114

(5x+54):9x1:47=5x+54:423=105-2

5x+54=423x103

5x+54=43569

5x=43569-54

5x=43515impartim prin 5 ⇒x=8703

Answer 2

Răspuns:

X=9    ;3

Explicație pas cu pas:

{105-[25:(45:x)+72:12]:47}+684:6=116

{105-[25:(45:x)+6]:47}+114=116

105-[25:(45:x)+6]:47=116-114=2

105-[25:(45:x)+6]=2x47=94

25:(45:x)+6=105-94=11

25:(45:x)=11-6=5

45:x=25:5=5

x=45:5

X=9
