Question

Solve the following word problems. Be sure to label the unknowns and to show the equation you use for the solution.

The sum of two consecutive integers is 145. Find the two integers.

Answer 1

Let the integers be x and (x + 1).

x + (x + 1) = 145
2x = 144
x = 72

integers are 72 and 73

Answer 2

if the smaller integer is N then the next consecutive integer is N+1
the sum of both integers is N + N +1 = 145

2N = 145 - 1 = 144 N = 144/2 N= 72 and N + 1 = 73
