Question

x = −5 can be expressed as a linear equation in 2 variables.

• A. 1x+1y=5
• B. 1x+0y= -5

Answer 1

The correct option is B

1x+0y= -5

A linear equation in two variables is of the form ax + by + c = 0, where a and b are both non-zero. If any one of a or b becomes 0, it would reduce to a linear equation in one variable. So, the equation x = -5 cannot be expressed as a linear equation in 2 variables.
