You are in line at a ticket window. There are two more people ahead of you in
line than there are behind you.
In the entire line, there are three times as many people as there are behind you.
how many are in the line?
:
Let x = no. behind you
then
(x=2) = no. ahead of you
:
Write an equation for the statement:
"there are three times as many people as there are behind you."
x + 1 + (x+2) = 3x
2x + 3 = 3x
3 = 3x - 2x
x = 3 people behind you
then
3 + 2 = 5 people ahead
:
Total: ahead + you + behind:
5 + 1 + 3 = 9 folks in line
