How can I solve following equations?
1) ((20+h)h)^1.666 / (4.828h+20)^0.666 = 2.846
----
I graphed the left side and the right side separately
and found their point of intersection.
I got h = 0.31452...

==============================

2) y^3-0.785y^2+0.026=0
Same process. I got y = 0.213247 or y = -0.165399 or y = 0.737153
