Plug in the value and check.
-2%3C=3%28-4.2%29-4
-2%3C=-12.6-4
-2%3C=-16.6
True or false?
If it's true, then it's a solution.
If it's false, then it's not a solution.

-2<=3x-4 Plug in value for x.
-2<=3(-4.2)-4
-2<=-12.6-4
-2<=-16.6 FALSE x=-4.2 is not a solution for the equation: Using the value -4.2 for x does not produce a true equation.
