Chapter-8 Linear Equations

About RS Aggarwal Solutions for Class 8 Maths Chapter-8 Linear Equations

A linear equation is an algebraic equation in which the highest power of the variable(s) is 1. It represents a straight line when graphed on a coordinate plane. A linear equation typically takes the form:

ax + b = 0

Here, 'x' is the variable, 'a' and 'b' are constants, and 'a' must not be zero (as division by zero is undefined).

Linear equations can also have multiple variables. In such cases, the equation takes the form:

a?x? + a?x? + ... + anxn + b = 0

where 'x?', 'x?', ..., 'xn' are variables, 'a?', 'a?', ..., 'an' are constants, and 'b' is a constant term.

The goal in solving a linear equation is to find the value(s) of the variable(s) that satisfy the equation. This is achieved by performing various algebraic operations to isolate the variable on one side of the equation.

For example, let's consider the equation 2x - 3 = 5. To solve for 'x', we can add 3 to both sides of the equation, which gives 2x = 8. Then, by dividing both sides by 2, we find x = 4.

Solving linear equations is a fundamental skill in mathematics and has numerous applications in various fields, such as physics, engineering, economics, and everyday problem-solving. It allows us to determine unknown values or relationships between variables.
