It's the first step.4x-x-2+6=6x+16 ##substract 2 rather an add 2
Check it carefully next time.!!
F(2y + 1) is 2

for this question
A reasonable number between 18 and 23 is 20. 69 minutes is 3 times 23 minutes, so we multiply the 20 by 3, getting an estimate of 60 cars.
One number be x
x+(x+1)+(x+2)=63
x+x+1+x+2=63
3x+3=63
3x=63-3
3x=60
x=60:3
x=20
smallest number = x=20
middle <span>number = x+1= 20+1=21
</span>largest<span><span><span> number = x+2</span> =20+2= 22</span>
</span>
They are equivalent
30:12 => 5:2
40:16 => 5:2
hope this helsp
