s=-9.9+6.3+|6.3|-8.7
Consider the fourth equation. Insert the known values of variables into the equation.
s=-3.6+|6.3|-8.7
Add -9.9 and 6.3 to get -3.6.
s=-3.6+6.3-8.7
The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 6.3 is 6.3.
s=2.7-8.7
Add -3.6 and 6.3 to get 2.7.
s=-6
Subtract 8.7 from 2.7 to get -6.
t=-6
Consider the fifth equation. Insert the known values of variables into the equation.
p=6.3 q=-8.7 r=-9.9 s=-6 t=-6
The system is now solved.
