Linear Equation in Two Variables

Linear Equation in Two Variables

1. Any equation which can be put in the form ax+by+c=0, where a, b and c are real numbers and a and b are both non-zero, is called a linear equation in two variables

2. Linear equation in two variables may have more than one solution

   • Ex: 1.2s+3t=5, p+4q=7 et cetera

3. Linear equations in one variable have one and only one solution

   • 2x+8-4=6

4. Solutions of linear equations dose not change when the same number is substracted or added to both LHS and RHS

   • or when you multiply or divide both side by non-zero number
