26=5+10+c
Consider the first equation. Insert the known values of variables into the equation.
26=15+c
Add 5 and 10 to get 15.
15+c=26
Swap sides so that all variable terms are on the left hand side.
c=26-15
Subtract 15 from both sides.
c=11
Subtract 15 from 26 to get 11.
P=26 a=5 b=10 c=11
The system is now solved.
