Sagot :
[tex]\frac{N}{5}^{(2}-\frac{5N}{10}=\frac{1}{5}^{(2} -we \ bring \ to \ the \ same \ denominator \\\\\ 2N-5N=2 \\\\ -3N=2 \\\\ \boxed{N=-\frac{2}{3}}[/tex]
N/5 - 5N/10 = 1/5
Multiply each side by 10 :
2N - 5N = 2
Combine the left side: 2N - 5N = -3N
So the equation now says -3N = 2
Divide each side by -3 : N = -2/3
