The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2.

Chapter 4: Linear Equations in Two Variables (a + b)2 = a2 + 2ab + b2 (a – b)2 = a2 – 2ab + b2 (a + b) (a – b) = a2 -b2 (x + a) (x + b) = x2 + (a + b) x + ab. (x + a) (x – b) = x2 + (a – b) x – ab. (x – a) (x + b) = x2 + (b – a) x – ab. (x – a) (x – b) = x2 – (a + b) x + ab. (a + b)3 = a3 + b3 + 3ab (a + b)

Definition: A linear equation is defined as an algebraic equation in which each term has an exponent of 1 and when graphed, the result is always a straight line. In other words, a linear equation is an equation with a maximum degree of 1.

Linear Equations in One Variable Class 7 Any equation is written in the form ax + b = 0 here, 'a' and 'b' are real numbers, and 'x' is a variable, called Linear Equation in one Variable. These equations have the variable of order one only. For example, 5x + 13 = 16 is a linear equation with a single variable.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

A linear equation is an algebraic equation in which each variable term is raised to the exponent or power of 1. A linear equation in one or two variables always represents a straight line when graphed. Example: x + 2 y = 4 is a linear equation and the graph of this linear equation is a straight line.
