What are two consecutive integers whose sum is 45?

Two consecutive integers means one is 1 more than the other integer. You can solve the problem by letting x represesnt one of the integers and x + 1 the next integer. Set up the equation and solve:

x + (x + 1) = 45 (next simplify)

2x + 1 = 45 (next subtract 1 from each side of the equation)

2x = 44 (next divide both sides of the equation by 2 to solve for the first integer)

x = 22 (this the first integer, the next is x + 1 which is 23)

The two integers are 22 and 23 (22 + 23 + 45).
