Main Concepts and Results
The word variable means something that can vary i.e., change and constant means that does not vary. The value of a variable is not fixed. Variables are denoted usually by letters of the English alphabets
such as x, y, z, l, m, n, p, a etc.
The expressions are formed by performing operations like addition, subtraction, multiplication and division on the variables and constants.
An equation is a condition on a variable (or variables) such that two expressions in the variable (variables) have equal value.
The value of the variable for which the equation is satisfied is called the solution or root of the equation.
An equation remains the same if the LHS and the RHS are interchanged.
In case of balanced equation if we (i) add the same number to both the sides, or (ii) subtract the same number from both the sides, or (iii) multiply both sides by the same non-zero number or (iv) divide
both sides by the same non-zero number, the balance remains undisturbed.
Transposing means moving from one side to the other. When a term is transposed from one side of the equation to the other side, its sign gets changed.
Transposition of an expression can be carried out in the same way as the transposition of a term.
To solve practical problems:
Read the problem carefully and denote the unknown quantity by variable x, y etc.
1) Form the equation according to the given conditions.
2) Solve the equation i.e., find the value of the unknown quantity (variable).
