Step1: Given,
The system of equation
a14c=3
c+4a=4
We have to solve this system by using any algebraicmethods.
Step 2: Explanation
We use a substitute method to solve the given system. From the first equation we have
a14c=314c=a3c=4(a3)
Put this value in the second equation,we get
c+4a=4
4(a3)+4a=4
4a12+4a=4
8a=4+12
8a=16
a=168
a=2
Now, c=4(a3)=4(23)=4×(1)=Hence the given system has unique solution and the solution is a=2 and c=4.Option(a) is correct.
