The equation is N = 4*M.
No, an equation needs an "=".
Such an equation has a total of six roots; the number of real roots must needs be even. Thus, depending on the specific equation, the number of real roots may be zero, two, four, or six.
That exists
What can be eliminated in. there is a situation that exists that needs attention
The equation needs an answer for it to be an equation in the 1st place. You bring the answer back to equation to show it's complete
