# Please see the bellow simulteneaus equation and help me please. I am confused. Thanks in advance.

20x-y=5
x+5y=10

I think the equations may be incorrect.
i think x=1,96 and n=0,348
am i right dear professors
it is a simultaneous equation Mam.

thanks
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.

20x-y=5
x+5y=10

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.

20x-y=5
x=10-5y
20(10-5y)-y=5
200-100y-y=5
200-101y=5
-101y=5-200
-101y=-195
y=195/101=1.93
20x-1.93=5
20x=6.93
x=6.93/20 =0.347
