10n=21
Consider the first equation. Multiply 4 and \frac{5}{2} to get 10.
n=\frac{21}{10}
Divide both sides by 10.
o=\frac{21}{10}
Consider the second equation. Insert the known values of variables into the equation.
p=\frac{21}{10}
Consider the third equation. Insert the known values of variables into the equation.
n=\frac{21}{10} o=\frac{21}{10} p=\frac{21}{10}
The system is now solved.
