Answer 2

A linear equation in two variables of the following is option (i) x+ y = 10.

• The equation x+y=10 has two variables x and y that are added and equated to a constant 10.
• The second option xy=10 is not a linear equation because the two variables x and y are multiplied.
• The third option x/y=10 is also not a linear equation because the variables x and y are divided. The equation can also be written as xy⁻¹=10.
• The fourth option 2x+3y is not equated to a constant and that is why it does not form a linear equation.
