There is one and only one real solution, and no imaginary solutions, of the equation x13 = 1. The solution is x = 1. If x = -1 then x13 = -1, so that does not work. If x = i, then x13 = -i, so that does not work. If x = -i, then x13 = -i, so that does not work.
a equals 5
-2 plus 5 equals +3
12 + 5 equals...
A is 14
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
x= -.5
