Steps:
1. Read the problem carefully and note down what is given and what is required.
2. Select a letter say x or y or z to represent the unknown quantity asked for.
3. Represent the word statements of the problems in the symbolic language step by step.
4. Look for quantities which are equal as per conditions given and form an equation.
5. Solve the equation.
6. Verify the result for making sure that your answer satisfies the requirements of the problems.

Example:
Five years ago the age of a father was twice the age of his son. The sum of their present ages is 55 years. Find their present ages.
Solution:
The age of the father, 5 years ago = x years
Age of the father 5 years ago = 2x years
Present ages of son and father respectively are (x+5) years and (2x+5)years.
Given that, sum of their present ages = 55 years
Therefore (x+5)+(2x+5) = 55
3x + 10 = 55
3x = 55 - 45
3x = 45
x = 45/3
x = 15

Verification:
Present age of son = x + 5 = 15 + 5 = 20 years
Present age of father = 2x + 5 = 2*15 + 5 = 30 + 5 = 35 years
The sum of their present ages = 20 + 35 = 55 years.
