Solving Linear Equations
In this Class 9 Mathematics topic from the chapter “Linear Equations in One Variable,” students learn how to solve equations systematically by performing the same operation on both sides. They work with constants, variables, fractions, brackets, and transposition, then verify solutions by substitution. The topic also develops the ability to translate simple word problems into linear equations and interpret the value of the unknown in context.

If 2x + 6 = 14, then what is the value of x?
The governing concept is solving a linear equation in one variable by maintaining equality on both sides. Starting with 2x + 6 = 14, subtract 6 from both sides: 2x = 8.
