8 + x = 13 + 2x
x - 2x = 13 - 8
-x = 5
x = -5
Given

first, convert

to base 25 to match the other term.



Substitute above identity into original equation:

Use substiution

above equation becomes
2/u-3u=1
multiply by u and solve for u:

=> u=2/3 or u=-1
case A:. u=2/3 =>

=>

case B: u=-1 =>
which does not give a real solution, so reject.
See graph below for confirmation of solution.
