First integer: x
Second integer: x + 1
Third integer: x + 2

Twice the second: 2(x + 1)
...and increased by the first: 2(x + 1) + x

is (meaning equals) 35, so:

. Just solve for x to get the first integer and the other two follow.

3 consecutive odd integers whose sum is 171.

First odd integer: x
Second odd integer: x + 2
Third odd integer: x + 4, so

, solve for x to get the first integer.
