Question

The equation $x=7$in two variables , can be written as:

• A. $1.x+1.y=7$
• B. $1.x+0.y=7$
• C. $0.x+1.y=7$
• D. $0.x+0.y=7$

Answer 1

The correct option is B

$1.x+0.y=7$

Explanation of correct option:

Option (B): $1.x+0.y=7$

The linear equation in two variables is given in the form of $ax+by+c=0$

Let the given equation $x=7$be written as;

$1.x+0.y-7=0or1.x+0.y=7$

Hence, the linear equation $x=7$ be written as $1.x+0.y=7$.

Therefore, option (B) is the correct solution.
