Answer 2

Given: Four options are given with different types of equations and inequalities.

To find: The one which is a linear equation in two variables

Explanation: A linear equation is a type of equation in which there is an "equal to(=)" sign and the maximum power of the variables is 1.

In option (a), the maximum power is 1 and it contains equal to sign. It also has only two variables x and y.

In option (b), the maximum power is 1 and it contains equal to sign but it has only one variable x.

In option (c), the maximum power is 1 but it does not contain equal to sign. Moreover, it only has one variable x.

In option (d), the maximum power is 2 and it contains equal to sign. Moreover, it has only one variable x.

Therefore, option (a) 3x+5y=8 is a linear equation in two variables.
