There are 120 solutions.
The person or program that solves the equation does.
If x = y, then the equation is true for any integer pair. Otherwise, the equation is not equivalent and is impossible.
A negative integer. Every time.
Any positive integer plus any negative integer will always equal an integer. The results will be either a positive integer, a negative integer or zero.it depends which is bigger. if the positive integer is bigger the answer will be positive. and if the negative integer is bigger the answer will be negative.
The quadratic equation will have two solutions.
You will get a positive integer. If you subtract a negative number, you will be adding it. I think of it like 2 minuses equals a plus. :P
There are no solutions because the discriminant of this quadratic equation is less than zero
using the t-table determine 3 solutions to this equation: y equals 2x
This equation describes all the points on the unit sphere. There is an infinite number of solutions. Some quick integer solutions would be (1,0,0) and (0,1,0) and (0,0,1) which are the one the axes.
