A=14-7
Consider the first equation. Subtract 7 from both sides.
A=7
Subtract 7 from 14 to get 7.
a=7
Consider the second equation. Insert the known values of variables into the equation.
b=7
Consider the third equation. Insert the known values of variables into the equation.
A=7 a=7 b=7
The system is now solved.
