Nice solution
1 0 x 2 = 1 0 0 x 3 1 0 0 x 3 − 1 0 x 2 = 0 1 0 x 2 ( 1 0 x − 1 ) = 0 1 0 x − 1 = 0 x = 1 0 1 = 0 . 1
10x^2=100x^3
10/100=x^3/x^2
1/10=x
Excellent straight-forward solution. Remember, you're using the fact that x is not equal to 0 to perform the division step!
Other than that, this looks great.

Divide both sides by 10x^2. You get 1=10x. Divide both sides by 10, you get x=0.1
