Question

Find three consecutive odd integers such that 10 times the first, plus 10 times the second, equals 10 more than 10 times the third. What is the third number

Answer 1

Answer:

4

Step-by-step explanation:

If x is the third number, then x−1 and x−2 are the second and first numbers.

10(x−2) + 10(x−1) = 10 + 10x

x − 2 + x − 1 = 1 + x

2x − 3 = 1 + x

x = 4
