Hi Ahmad;
Please proofread this question.
I think the equations may be incorrect.
I understand it is simultaneous.
I tried to resolve.  I might be making a mistake, or perhaps the equations are copied incorrectly.  Please re-check equations.

100x-5y=25
     x+5y=10
101x=35
x=35/101
substitute in second equation
35/101+5y=1010/101
5y=975 /101
y=195/101
What is the obsession with approximate answers when accurate ones are easily available?

Yes, I noticed that and changed it before I submitted but somehow the previous answer is the one that got posted. Not sure how that happened.
