How do I solve this simultaneous equation?

frostfly

h = 50 + 2T - 4.9T²
h = 20t - 4.9T²

What do I do oh what do I do? :cry:

Do you mean three separate variables: h, T and T2? Or is "T2" actually "T²"

is there a difference between t and T is what he's asking, i.e: have you made a typo by writing t in lowercase in the second equation?

If so, just equate the two experssion you have for h together and solve for T as a quadratic.

Both equations are equal to h, so set them to be equal to one another. From there it's just a matter of solving the equation, a process with which I presume you are already familiar?
