Question

Find two consecutive integers whose sum is 113. which of the following equations could be used to solve the problem? 2x = 113 2x 1 = 113 2x 2 = 113 x2 1= 113

Answer 1

Answer:

Option 2nd is correct

$2x+1 = 113$

Step-by-step explanation:

Let two consecutive integers are x and x+1

As per the statement:

The sum of two consecutive integers is 113

⇒$x+(x+1) = 113$    

⇒x+x+1=113                              ....[1]

Like terms are those which have same variable to the same power.

Combine like terms in [1] we have;

$2x+1 = 113$

Therefore, the following equations could be used to solve the problem is, $2x+1 = 113$

Answer 2

Let the two integers be x and x + 1, then
x + x + 1 = 113
2x + 1 = 113
