Ok, so she has 14 tickets and each ride cost 2 so that can be modeled with the following expression: x= 14-2y since she initially bought 14 tickets and 2 times the number of tickets she spends. To find the equivalent expression you could basically switch up the formula like so: 7*2-2y=x because you just need an equivalent expression, and you don't need to have such a different formula or anything like that. Hope I helped!

Find the value of the variable using these steps.

$0.4x+3.9=5.78$ ⇒ subtracting 3.9 form both sides

$0.4x+3.9-3.9=5.78-3.9$

$0.4x=1.88$ ⇒ Divide both sides by 0.4

$\frac{0.4x}{0.4}= \frac{1.88}{0.4}$

$x=4.7$
