I am a five digit number greater than 20000 but less than 30000 my ones digit is three more than my thousand digit. all my other digit are the same. the sum of my digit is 10. what -2 = 1 over 1+x (-) 3 over 1-x

I have:

-2(1-x)(1+x) = 1-x-3(1+x)

-2(1+x-x-x^2) = 1-x-3-3x

-2-2x+2x+2x^2 = -2-4x

-2+2x^2 = -2-4x

2x^2+4x-2 = -2
