VA ROG DAU CORONITA !!!!

Answer 1

Răspuns

Explicație pas cu pas:

1 + {2 x [ 3 + ( n - 4 ) x 5 ] : 6 } x 7 = 8  

{2 x  3 + ( n - 4 ) x 5 ] : 6 } x 7 = 8   - 1

{2 x [ 3 + ( n - 4 ) x 5 ] : 6 } x 7 = 7

2 x [ 3 + ( n - 4 ) x 5 ] : 6  = 7 : 7

2 x [ 3 + ( n - 4 ) x 5 ] : 6 = 1

2 x [ 3 + ( n - 4 ) x 5 ]  = 1 x 6

2 x [ 3 + ( n - 4 ) x 5 ]  = 6

3 + ( n - 4 ) x 5  = 6 : 2

3 + (n - 4) x 5 = 3

(n - 4) x 5 =  3 - 3

( n - 4) x 5 = 0

n - 4 = 0 : 5  

n - 4 = 0

n = 0 + 4

n = 4

Răspuns

1 + {2 x[ 3 + ( n - 4 ) x 5 ] : 6 } x 7 = 8

{2x[3(n-4)x5]:6}x7=8-1

2x[3+(n-4)x5]:6=7:7

2x[3+(n-4)x5]=1x6

3+(n-4)x5=6:2

(n-4)x5=3-3

n-4=0:5

n=0+4

n=4
