Question

Find two consecutive odd integers whose sum is 36

Which of the following equations could be used to solve the problem

2x=36
2x+1=36
2x+2=36
x^2+2=36

Answer 1

2x + 2 = 36

Explanation:

Two consecutive odd intergers: x, x + 2.

The sum: 36

The equation:

x + (x + 2) = 36

x + x + 2 = 36

2x + 2 = 36 subtract 2 from both sides

2x = 34 divide both sides by 2

x = 17

x + 2 = 17 + 2 = 19
