One-Variable Equations
Overview
We can solve one-variable equations and inequalities by plugging in the unknown
number. For example…
In which equation does x = 4?
A. 2 + x = 4
B. 2 + x = 6
Since we know the value of x, we simply need to plug it into each equation to see if it gives us the correct result.
Choice A is incorrect because we do not get the correct answer when we plug the number in for x.
Choice B is correct because we do get the correct answer when we plug the number in for x.
