The equation that can be used to solve the problem is 2x + 1 = 73 ( option D)
Word problem is a way of putting mathematical equation in words. To solve, this words are interpreted in to mathematical equation.
Represent the first integer by x
therefore the second consecutive integers will be x + 1
The sum of these integers is 73
therefore;
x + x + 1 = 73
2x + 1 = 73
therefore the equation to solve the problem is 2x + 1 = 73
x = 72/2 = 36
therefore the numbers are 36 and 37
