x is an unknown number/fraction which needs to be solved.
The equation is N = 4*M.
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.
No, an equation needs an "=".
That exists
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
It needs to be balanced.
