Your answer is 41.93529593 or 41.9
Bro I’m rly sorry but I don’t know the answer to this
For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
100
6738 —> 7000
5903 —> 6000
7000 - 6000 = 1000
