Answer 2

a) \(x+1=35:7+5\)

\(\Rightarrow x+1=5+5\)

\(\Rightarrow x+1=10\)

\(\Rightarrow x=10-1\)

\(\Rightarrow x=9\)

Vậy x = 9

b) \(x:3=45:5\)

\(\Rightarrow x:3=9\)

\(\Rightarrow x=9\times3\)

\(\Rightarrow x=27\)

Vậy x = 27

Answer 3

1, x+1 = 35:7+5

x+1=5+5

x+1=10

x=10-1

Vậy x =9

2, x:3=45:5

x:3=9

x=9×3

x=27

Vậy x=27

Answer 4

1, x + 1 = 35 : 7 + 5

x + 1 = 5 + 5

x + 1 = 10

x = 10 - 1

x = 9 

2, x : 3 = 45 : 5

x : 3 = 9

x = 9 x 3 

x = 27

Answer 5

 x+1 = 35:7+5

x+1=5+5

x+1=10

x=10-1

Vậy x =9
