MCQ
The equation $x = 7$ in two variables can be written as
- A$0.x + 0.y = 7$
- B$1.x + 1.y = 7$
- C$0.x + 1.y = 7$
- ✓$1.x + 0.y = 7$
✓
Answer
Correct option: D.
$1.x + 0.y = 7$
The equation $x = 7$ in two variables can be written as exactly $1.x + 0.y = 7$.
because it contain two variable $x$ and $y$ and coefficient of $y$ is zero as there is no term containing $y$ in equation $x = 7.$
because it contain two variable $x$ and $y$ and coefficient of $y$ is zero as there is no term containing $y$ in equation $x = 7.$
