Question

(i) Which of the following is a linear equation in two variables

a) 2 + 1 = 2 + 3 b) 3 + 7 =

2 + 5

c) 3 − 1 = 7 − 5 d) 2 − 15 = + 11

(ii) Write a linear equation in two variables using the data “a number

is equals to 3 more than 2 times the other number ”

(iii) The equation − 5 − 7 = 0 has the following as solution

a) = 1 , = −1 b) = 2 , = −1

c) = −2 , = 1 d) ,

(iv) A two digit number whose Units digit is ‘x’ and Tens digit is ‘y’. If it is

reversed the sum of two numbers is 121. Write a linear equation in two

variables using it​

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 and . Linear equations are also first-degree equations because the exponent on the variable is understood to be 1.
