s=9-9
Consider the first equation. Subtract 9 from both sides.
s=0
Subtract 9 from 9 to get 0.
t=0
Consider the second equation. Insert the known values of variables into the equation.
u=0
Consider the third equation. Insert the known values of variables into the equation.
s=0 t=0 u=0
The system is now solved.
