In this video we will learn about the basics of Linear Equations in two variables.

In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

Sometimes in mathematics we like to use letters to represent numbers. The ‘value’ of these letters can change according to certain rules or conditions we are given – hence we can call them variables.

What is a linear equation? Linear equations are frequently used to compute rates such as speed, time and distance problems. As a standard form of a linear equation in one-variable, this rule has the ...

The efficiency gain of seemingly unrelated regression (SUR) relative to OLS is a decreasing function of correlation of variables across equations. This article examines the efficiency gain for an ...

This is a preview. Log in through your library . Abstract We develop an algorithm for solving a system of diophantine equations with lower and upper bounds on the variables. The algorithm is based on ...
