I am curious as to how i am to solve and equation with a negative exponent.

My problem is:

10e^x-15-45e^-x=0

We are suppose to use the formula that u=e^x.

I don't know what to do since there is a negative after the 45.

Can you explain the method you used so that i can use it on future problems? I am confused on how the x's transfered
