Odd integers are 2 apart
the 3 consecutive odd numbers are x,x+2, x+4
sum is x+x+2+x+4 or 3x+6
the sum is 15 more than 2 times middle one
3x+6=15+2(x+2)
3x+6=15+2x+4
3x+6=19+2x
minus 2x both side
x+6=19
minus 6 both sides
x=13
x+2=15
x+4=17
they are 13,15,17
This is an example of the Distributive property
we are given

Since, every value is in ft
so, we can take out ft

now, we can add them
and we get
