If x is the number of tickets she has left, then 2x is the number she has used (2×number of rides she has gone on). So the number she has left would be...
14 - 2x
We can now find an equivalent expression by replacing the x with a number... for example...
14 - 2(2)
This would be if she rode two rides. You could solve the equation like this...
14 - 2x =
14 - 2(2) =
14 - 4 = 10
After 2 rides she has 10 tickets left.
