Step 1: Given
3xx=3
Step 2: Solution
3xx=3
Adding x
3x=3+x
Squaring both sides
3x=(3+x)23x=9+x2+6x
x2+7x+6=0
(x+1)(x+6)=0
x+1=0, x+6=0
x=-6, -1
Check
For x=-3
366
=3+6=93
Not a solution
For x=−1
311
=4+1
=2+1
=3
which is same as right side
Answer: x=−1

Determine all positive numbers a for which the curve y = a x intersects the line y = x without calculus
The answer is 0 < a < e 1 / e , but how to find it? Is it a system of equations? Which ones? I just need an idea at least, because I'm stuck. If it is impossible without calculus, solve it with it.
