Treat it like a regular algebra problem.
Here's a hint, there will be division and an inverse function.
1. Divide 5
2. Arc Cosine
3. Subtract 3
4. Answer is -1.63 (the first solution)
However the solution page shows 1.914 and 4.653.
Yeah ... there's something not right there, are you sure you checked the right solutions against the exercise ?
