Answer:
A,C and E have solution x=4
B and F have solution x=0
Explanation:
We have to find the equations which have same solution.

A,C and E have same solution because when we substitute x=4 then it satisfied the given equations.It does not depend on solving the equations.
B and F have same solution because when we substitute x=0 then it satisfied the given equations.
