Question

Which one of the following is a solution of the linear equation 5 + 4 = 6?

(a) 2, 1 (b) 1, 2 (c) −2, 1 (d) 2, −1​

Answer 1

Answer:

A linear equation in one variable is an equation that can be written in the form ax+b=c, where a,b, and c are real numbers.  

option (a) has two variables x and y.Hence it is a linear equation with two variables.

Option (b) has one variable t.Hence it is a linear equation with one variable

Option (c) and (d) is not a linear equation ∵ the highest power of x is 2.
