Important Formulas: Linear Equations in One Variable

# Important Formulas: Linear Equations in One Variable - The Complete SAT Course - Class 10

## Algebraic Equation

An algebraic equation is an equality involving variables. It says that the value of the expression on one side of the equality sign is equal to the value of the expression on the other side.

### What is Linear equation in one Variable

We will restrict the above equation with two conditions
or
An equation of the form ax + b = 0, where a and b are real numbers, such that a is not equal to zero, is called a linear equation in one variables

### Important points to Note

1. These all equation contains the equality (=) sign.
2. The expression on the left of the equality sign is the Left Hand Side (LHS). The expression on the right of the equality sign is the Right Hand Side (RHS)
3. In an equation the values of the expressions on the LHS and RHS are equal. This happens to be true only for certain values of the variable. These values are the solutions of the equation
4. We assume that the two sides of the equation are balanced. We perform the same mathematical operations on both sides of the equation, so that the balance is not disturbed. We get the solution after generally performing few steps
5. A linear equation in one variable has only one solution
