    Which of the following solutions do the system of equations\[2x+y=5\]and\[x+2y=4\]have?

    A)  Consistent and a unique solution

    B)  Consistent and infinitely many solutions

    C)  Inconsistent

    D)  No solution

    Correct Answer: A

    Solution :

     Given equations are                 \[\text{216 }=\text{ 192 }\times \text{ 1 }+\text{ 24}\] and        \[\text{192 }=\text{ 24 }\times \text{ 8 }+\text{ }0\] Here    \[{{6}^{x}}\] and        \[{{6}^{x}}={{(2\times 3)}^{x}}={{2}^{x}}\times {{3}^{x}}\] \[\Rightarrow \]               \[{{6}^{x}}\] Hence, the given equations have a unique solution and are consistent.
