X is bundled up in that e^ function. So the first thing we want to do is to get that e^ by itself. Subtract 50 from both sides to get
-e-0.2x = 150
A negtaive exp function is fine, but I like to make them positive, so multiply both sides by -1
e-0.02x = -150
To get the exponent down, we need to take the natural log of both sides. Note that ln(eanything) = anything.
-0.02x = ln(-150)
Now we have a problem. The natural log of a negative number is undefined. As it stands, there are no solutions.
Can you check the given problem and report back?
