What is a Linear Equation<\/strong><\/h2>\n

Let us consider a small puzzle: Think of a number and add 7 to get 12. What is the number?
\nWe can easily say that the number must be 5.
\nIf we use a letter, i.e., (variable) to stand for the unknown number, we can write this puzzle as follows:
\nx + 7 = 12 \u00a0 \u00a0 \u00a0 \u00a0 …(1)
\nHere, if x = 5, 5 + 7 = 12. So, x = 5 is the unknown number which satisfies the statement (1). This is nothing but an equation. An equation is a mathematical statement equating two expressions. The expression on the left side of the equal sign is called LHS (Left Hand Side) and the expression on the right side of the equal sign is called RHS (Right Hand Side). The expressions on either side of equal sign are called members of the equation.<\/p>\n

An equation which involves a variable with the highest power 1 is called a linear equation<\/strong>.
\nExamples:<\/strong> 2x + 3 = 7, x + y = 9, a + b = 2.5 are examples of a linear equation.
\nBut, what about x2<\/sup> + 4 = 13? Is it a linear equation? No because variable x has its power 2.<\/p>\n
