Linear Equation

A linear equation is an equation which only involves linear combinations of variables. A collection of such equations is a linear system.

A linear equation can be defined as:

$$a_1{x}_1+a_2{x}_2+a_3{x}_3+\dots a_n{x}_n=b$$

• $a_1,a_2,\dots a_n$ = Coefficients
• $x_1,x_2,x_3\dots x_n$ = Variables (does not have to be $x$, can be $y,z,\omega ,\alpha$, etc.)
• $b$ = Constant term
