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

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
