I do it by using an "if/then" statement. The variable behind the "if" statement is the independent variable. The variable behind the "then" statement is the dependent variable. Example: y = 3x3 + 4x2 - 6x +1 So if you tried "if y = 2", you're still stuck on your "then" statement. You don't really know what x is, do you? But if you try "if x = 1", then you can determine right away that y = 2. So x is your independent variable and y is your dependent variable.
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.
