The five problems are not easy but could all be solved quickly enough by pattern discovery and application of suitable techniques. This set of solutions is rich in learning. The solutions and concepts are explained in details. Important concepts used are mathematical reasoning, pattern discovery, strategy of algebraic expression simplification, double componendo dividendo, adapted componendo dividendo, zero valued factoring, and coefficient comparison of like terms. The Concepts and Techniques form the BASIC SKILLSET for solving harder algebra problems EASILY IN MIND.

These are the first 5 questions 1 to 5 and form the 1st part of video on the article **SSC CGL Solution set 35, Algebra 10 from SureSolv.com.**
