Question

Sum of two consecutive number is 71.find the number

Answer 1

Answer:

• SOLUTION: find two consecutive number whose sum is 71 Let x = the first number Let x+1 = the second number and their sum is 71 So, x +(x+1) = 71 2x+1= 71 Subtract 1 on both sides.

Answer 2

Let x = the first number

Let x+1 = the second number and their sum is 71

So, x +(x+1) = 71

2x+1= 71

Subtract 1 on both sides

2x+ (1-1) =71-1

2x =70

divide 2 on both sides

2x/2 = 70/2

x = 35

If x = 35 then x+1 =36

Therefore the consecutive numbers are 35, 36
