Question

What is a linear equation?

Answer 1

A linear equation is an algebraic expression that includes variables with exponents of 1. All equations that follow this rule are named linear. Examples of linear equations are

`\begin{gathered} y+x=4 \\ 3x-5y=8 \\ (4)/(3)x+y=(5)/(2) \end{gathered}`

Notice that each variable has an exponent of 1, that's why these equations are linear.
