I assume you are supposed to solve for x. In that case, lets just do a few things. multiply both sides by x, getting xe^2(what happened to the negative?) = 5x - 1

then subtract 5x from both sides getting xe^2 - 5x = -1

then multiply everything by one: 5x - xe^2 = 1(why cant we just add one to each side?

Your teach said to evaluated to the nearest 100th, so lets just make e^2

be 7.3890561 (and we will round at the end).

so we have 5x - 7.3890561x = 1

thus, -2.3890561x = 1

and now x = 1/-2.3890561 = -0.418575.....

You are asked to report your answer to the nearest 100th, so lets go with **x = -0.42** (note that rounding to the nearest 100th simply means report two digits (rounding the second one if necessary) after the decimal point.
