Who can solve for "x" the fastest?
3(x+2) = 9
Ofcourse this one is easy, so feel free to give your own aswell.
I'd expect that it'll be expand the equation before the equals, and then solve it by moving everything over so:
3x+6=9 (once expanded)
3x = 9-6 (moved over)
x = 3/3
x = 1

Thats a thing I dont even solve but just see.
Anyone older than 12 who cant solve this correctly should probably be worried about his future in maths.
When reading the title I was hoping for some more spaced stuff.
Heres your level 2:
Who can solve this for x the fastest?
1.4x^5 - 0.3x^4 - x^3 + 17x - 1 = 0
First one to explain a possible way to solve this gets a friendly rep.
(Hint: solution dont need to be 100% exact, but exact enough, fast enough, and shouldnt require computers)

Isolate the 1.4x^5 - 0.3x^4 - x^3 by subtracting 17x - 1.
Cube root, combine like terms outside the radical, then divide by the radical.
Multiply x10 since the only term outside the radical is .1x
Stumped on this.
