You can put this solution on YOUR website!
Let's say you had the equation
But you were told that the variable  was restricted to non-negative real numbers. How many solutions would this equation have under that constraint? If z is positive, the -5z is negative, and adding -6 just makes it more negative. If z is zero, then -5z equals zero, and the entire left side equals -6, still negative and nowhere near 4. You can't get there from here, is the message.
Well,  , so there is no number that you can substitute for  that would make  a true statement.
