​

Answer 1

Răspuns:

Explicație pas cu pas:

[ 1+2*(6*6:b)-7]:6=2

1+2*(36:b)-7=2*6

1+2*(36:b)-7=12

1+2*(36:b)=12+7

1+2*(36:b)=19

2*(36:b)=19-1

2*(36:b)=18

36:b=18:2

36:b=9

b= 36:9

b=4

Answer 2

Explicație pas cu pas:

[1+2×(6×6:b)-7]:6=2

[1+2×(36:b)-7]:6=2

1+2×(36:b)-7=6×2

1+2×(36:b)-7=12

1+2×(36:b)=12+7

1+2×(36:b)=19

2×(36:b)=19-1

2×(36:b)=18

36:b=18:2

36:b=9

b=36:9

b=4

Răspuns: b=4
