| Assertion (A): \[\text{3x}-\text{4y}=7\] and \[\text{6x}-\text{8y}=\text{k}\] have infinite number of solution if \[\text{k}=\text{14}\]. |
| Reason (R): \[{{a}_{1}}x+{{b}_{1}}y+{{c}_{1}}=0\] and \[{{a}_{2}}x+{{b}_{2}}y+{{c}_{2}}=0\] have a unique solution if \[\frac{{{a}_{1}}}{{{a}_{2}}}\ne \frac{{{b}_{1}}}{{{b}_{2}}}\]. |
