MCQ
The equation $x =7$ in two variables can be written as
- A$1 \cdot x+1 \cdot y=7$
- B$1 . x+0 . y=7$
- C$0 . x+1 \cdot y=7$
- D$0 . x+0 . y=7$
✓
Answer
(b) $1 . x+0 . y=7$
Explanation: 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 $x=7$
