\r\n A linear equation is a polynomial equation that is linear in its constituent variable. Stated in simple words,\r\n it means that the highest power of the variable appearing in the equation is one.\r\n Let us give you an example. The equation \\( 3 x + 4 =0\\) is a linear equation in \\(x\\) since the highest power of the constituent variable i.e. \\(x\\)\r\n in the equation is one. Now, compare this to equation \\(4 x^2 + 3 x + 9 =0\\), which is not a linear equation in \\(x\\) because the highest\r\n power of \\(x\\) in the equation is greater than one.\r\n

\n The general form of a linear equation in a variable \\(x\\) is given by\r\n $$ m x + c = l$$\r\n where \\(m \\ne 0\\), \\(c\\) and \\(l\\) all are real numbers.\r\n

\n You can imagine the two sides of equation representing two sides of a scale. The solution of the equation\r\n corresponds to the value of variable \\(x\\) that balances the scale. The value of \\(x\\) can be determined in two steps.\r\n These steps involve carrying out the same set of operations on both sides of the equation to keep the scale balanced.\n
\r\n\r\n $$m x = l -c$$\r\n
\r\n$$x = \\frac{l -c}{m}$$
