Answer 1

let the first pages is x

Then second one is x+1

Therefore x + x+1 = 71

2x +1 = 71

2x = 70

x= 35

x+1 = 36

Answer 2

Answer :

• Let the first page be x
• Second page be x + 1

To find :

• The number of pages

According to the question,

↝ x + x + 1 = 71

↝ 2x + 1 = 71

↝ 2x = 71 - 1

↝ 2x = 70

↝ x = 70 ÷ 2

.°. x = 35

Now,putting the value of x.

• First page = x = 35.
• Second page = x + 1 = 35 + 1 = 36.
