u, the value of the ones digit
t, the value of the tens digit
The number is 10t%2Bu.

Managing the description:
system%28t=u-5%2C10u%2Bt-%2810t%2Bu%29=7%29

Next is to solve the system of equations for u and t.

IMPOSSIBLE! DO NOT even bother to try to solve this. There's absolutely no way you can, regardless of what the respondent below instructs

you to do. A person who knows anything about math should know this.

Difference between ORIGINAL and REVERSED numbers MUST BE A MULTIPLE of 9, and 7 is CLEARLY NOT a MULTIPLE of 9.
