MCQ
$a x+b y=c$ and $m x+n y=d$ and $a n \neq b m$ then these simultaneous equations have -
- ✓Only one common solution
- BNo solution
- CInfinite number of solutions
- DOnly two solutions
✓
Answer
Correct option: A.
Only one common solution
Given: $a x+b y=c$ and $m x+n y=d$
Then,
$\frac{a}{m} \neq \frac{b}{n}, \text { as an } \neq b m$
Now, we know that when the ratio of coefficients is not equal.
Equations will have unique solution. Hence, A is the correct answer.
