Question

find three consecutive odd integers whose sum is -33?

Answer 1

x + x + 1 + x + 2 = -33
3x + 3 = -33
3x = -33-3 = -36
x = -36/3
x = -12

So, answer is: -12,-11,-10

Answer 2

Easiert way would be this:
Take the integers as x-1, x and x+1
Their sum is 33.
You should be able to work out the algebra.
