Re: Equation
Hi wildmath;
First thing you know what z is so substitute that into your equation.
Divide both sides by 4.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
