how do you check an equation. So what we want to do is we want to figure out an x that satisfies this so theres some number that if I take five multiply it by that number subtract three from it thats going to be the same thing as if I take four times that number and add three to it. For symmetry with respect to the Y-Axis check to see if the equation is the same when we replace x.
Plug the solution back into the equation. Solve 3x 2 16. To determine if an equation is a linear function without graphing you will need to check to see if your function has the characteristics of a linear function.
Check that the y or independent variable is by itself on one side of the equation.
In this lesson you will learn how to identify the most efficient way to check your solutions to linear equations by thinking strategically.
