You need to substitute `1/e^x` for `e^(-x)` in the given equation such that:
`3*(1/e^x) - e^x = -2`
You need to move all terms to one side such that:
`3*(1/e^x) - e^x + 2 = 0`
You need to bring all terms to a common denominator such that:
`3 - e^(2x) + 2e^x = 0`
You need to rearrange the termsin descending powers of x such that:
`- e^(2x) + 2e^x + 3 = 0`
