**3. What are Linear Equations in Two Variables?**

Linear equations in two variables are equations in which the unknown variable is a linear function. The equation is written between two straight lines, and the form of the equation is an expression containing variables and constants that will be automatically displayed when solved. These types of equations can be difficult to work with because they often contain abstract functions such as y=ax + bx2, or x becoming negative due to its square root; these functions can make it difficult to predict what will happen when solving them. When solved, they produce three new variables on either side of this main equation which is found mathematically by substituting for one variable with its derivative.
