Question

What is leaner equations?

Answer 1

YOUR QUESTION IS WRONG. THERE IS NOTHING CALLED LEANER EQUATIONS. 
IT IS LINEAR EQUATIONS!!!!!!!!!!

A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: 

It has one or two variables.No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
