I believe the expression would be:
x+2
For example, if you have the odd number 3 as x, 3+2 would be 5, the next odd number.
Hope this helped!! xx
If you know that y = 6. You just have to switch Y by 6.
x + 2y = 16
x + 2*6 = 16
x + 12 = 16
x = 16 - 12
x= 4
4 + 2*6 = 16
Hope this helps !

15 km = 15,000 m
every 600 m, there is one water station (starting point at 600 m)
number of stations needed : 15000/600 = 25 water stations
Before we do any solving, we need to simplify both sides.
On the left, we can simplify -2x + 3x - 5 to x - 5.
On the right, we can simplify 6 - 21 to -16.
So we have x - 5 = -16.
Solving from here, we add 5 to both sides to get x = -11.
