## Resource summary

linear equations in two variables
1 Linear equations in one variable have one and only one solution.

Annotations:

• You have already learnt this!
1.1 2x+8-4=6 etc
2 Linear equations in two variables may have more than one solution

Annotations:

2.1 Ex: 1.2s+3t=5, p+4q=7 et cetera
3 Solutions of linear equations does not change when the same number is subtracted or added to both LHS and RHS
3.1 or when you multiply or divide both sides by a non-zero number
4 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.
