Question

Find two consecutive integers whose sum is 73.

Which of the following equations could be used to solve the problem?
2x = 73
2x + 1 = 73
2x + 2 = 73
x2 + 1= 73

Answer 1

First you have x.
Now consecutive means right after something, so you have x + 1 because it's right after x.

x+x+1 = 73
Add like terms and you get 2x + 1 = 73

Answer 2

ok thank you
