Answer:
No solution
Step-by-step explanation:
1) We will use the matrix method to solve this problem.
[tex]\left[\begin{array}{ccc}-2&1&1\\2&-1&3\\\end{array}\right][/tex]
2) Apply to Row2 : Row2 + Row1.
[tex]\left[\begin{array}{ccc}-2&1&1\\0&0&4\\\end{array}\right][/tex]
3) Since [0, 0, 4] is not true, this is an inconsistent system.
No solution
