Question

The linear equation $(2x+5y=7)$ has

• A. a unique solution.
• B. two solutions.
• C. infinitely many solutions.
• D. no solution.

Answer 1

The correct option is C infinitely many solutions.

$2x+5y=7$ is a single equation involving two variables.
Here for any value of $x$, there is a value for $y$ and vice-versa.
$\therefore 2x+5y=7$ has infinite number of solutions.
