While solving a pair of linear equations either we might get a solution or we might not get a solution. If we get a solution, then the pair of linear equations in two variables is called ...

About Class 9 Maths Chapter 4 Linear Equations in Two Variables In this chapter, you will get to learn about linear equations and their applications in real life problems.

Learn how to use inverse operations to find the value of an unknown variable in an equation, so that the value is true.

We develop an algorithm for solving a system of diophantine equations with lower and upper bounds on the variables. The algorithm is based on lattice basis reduction. It first finds a short vector ...

Equations such as 3𝑥 + 8 = 15 need two steps. Make sure you are confident in calculating with negative numbers, which is a skill often needed to solve equations.
