MCQ
$x = 5$ and $y = -2$ is the solution of the linear equation.
- A$x + 3y = 1$
- B$2x + y = 9$
- C$3x + y = 0$
- ✓$2x - y = 12$
✓
Answer
Correct option: D.
$2x - y = 12$
$x = 5$ and $y = -2$ is the solution of the linear equation $2x - y = 12$
$2x - y = 12$
$LHS = 2x - y$
$2.5 - (-2)$
$10 + 2$
$12$
$RHS = 12$
$LHS = RHS$
It means that $x = 5$ and $y = -2$ is the solution of the linear equation $2x - y = 12.$
$2x - y = 12$
$LHS = 2x - y$
$2.5 - (-2)$
$10 + 2$
$12$
$RHS = 12$
$LHS = RHS$
It means that $x = 5$ and $y = -2$ is the solution of the linear equation $2x - y = 12.$
