A=2-1
Consider the first equation. Subtract 1 from both sides.
A=1
Subtract 1 from 2 to get 1.
a=1
Consider the second equation. Insert the known values of variables into the equation.
b=1
Consider the third equation. Insert the known values of variables into the equation.
A=1 a=1 b=1
The system is now solved.
