2A=6-4
Consider the second equation. Subtract 4 from both sides.
2A=2
Subtract 4 from 6 to get 2.
A=\frac{2}{2}
Divide both sides by 2.
A=1
Divide 2 by 2 to get 1.
C=6-8
Consider the third equation. Subtract 8 from both sides.
C=-2
Subtract 8 from 6 to get -2.
2\times 1-2=a
Consider the first equation. Insert the known values of variables into the equation.
2-2=a
Multiply 2 and 1 to get 2.
0=a
Subtract 2 from 2 to get 0.
a=0
Swap sides so that all variable terms are on the left hand side.
A=1 C=-2 a=0
The system is now solved.
