Question

There are two consecutive odd numbers such that twice the smaller number plus one is ten more than the greater number. What is the smaller number?




7

9

11

13

Answer 1

Let the larger number be x and smaller one be y.
x=y+2
x+10=2y+1
x=2y+1-10
x=2y-9
2y-9=y+2
2y-y=9+2
y=11
Is that clear?
