Lets get started :)
We need to isolate t from x =

at²
Take 2 to the left-hand side { Do multiplication since you see division }
2x = at²
Take a to the left-hand side { Do division since you see multiplication }

= t²
Take square root since t is to the power of 2

= t
Isolate the variable Y by multiplying 1.5 on both sides.


Hope this helps.
頑張って!
