MCQ
$x = 5, y = 2$ is a solution of the linear equation:
- A$x + 2y = 7$
- B$5x + 2y = 7$
- ✓$x + y = 7$
- D$5x + y = 7$
✓
Answer
Correct option: C.
$x + y = 7$
Substituting $x = 5$ and $y = 2$ in $L.H.S.$ of equation $x + y = 7,$
We get:
$LHS$
$= 5 + 2$
$7 = RHS$
Hence, $x = 5$ and $y = 2$ is a solution of the linear equation $x + y = 7.$
We get:
$LHS$
$= 5 + 2$
$7 = RHS$
Hence, $x = 5$ and $y = 2$ is a solution of the linear equation $x + y = 7.$
