6 CBSE ALGEBRA Worksheet

6 CBSE ALGEBRA: Introduction

Algebra is a branch of mathematics that deals with variables and their relationships. It involves the use of symbols, equations, and formulas to solve problems.

Variables and Expressions

Variables: A variable is a symbol that represents a value that can change. For example, x, y, z, etc.

Expressions: An expression is a combination of variables, constants, and mathematical operations. For example, 2x + 3, x - 4, etc.

Simplifying Expressions

Like Terms: Terms that have the same variable and exponent are called like terms. For example, 2x and 3x are like terms.

Combining Like Terms: Like terms can be combined by adding or subtracting their coefficients. For example, 2x + 3x = 5x.

Equations

Equation: An equation is a statement that says two expressions are equal. For example, 2x + 3 = 5.

Solving Equations: Equations can be solved by adding, subtracting, multiplying, or dividing both sides of the equation by the same value.

Formulae

Linear Equations: A linear equation is an equation in which the highest power of the variable is 1. For example, 2x + 3 = 5.
