There are an infinite number of such equations.Here's one of them:2x + 6 = -x(Since the solution is only 1 number, theequation can only have 1 variable.)
That's when you say two or more things that cannot both be true, such as, "The one and only solution is 3," and, "The one and only solution is 17."
row reduce the matrix in question and see if it has any free variables. if it does then it has many solution's. If not then it only has one unique solution. which is of course the trivial solution (0)
The solution to a system on linear equations in nunknown variables are ordered n-tuples such that their values satisfy each of the equations in the system. There need not be a solution or there can be more than one solutions.
A system of linear equations can only have: no solution, one solution, or infinitely many solutions.
Pyramid sudoku is a regular sudoku board with shaded areas. Not only does one need to complete the regular sudoku, but the shaded areas can only have 1-9 as well.
There is only one way to correctly fill a sudoku.
If you are referring to published Sudoku puzzles, the answer is No. These are generally designed to have exactly 1 solution. That fact can sometimes help solve a Sudoku by eliminating choices that create non-unique configurations. If you are asking about possible Sudoku boards, the answer is yes - there are many more possible sudoku puzzles with multiple solutions than with unique ones. Details and examples can be found at the related link.
One can become better at completing Sudoku puzzles by practice. Start with the beginner puzzles and work the way up to higher tiers of challenge. Remember that in a Sudoku puzzle with in the block, numbers can only be used once and with-in each line - vertical or horizontal, numbers again will only be used once in some sort of sequence of 1-9.
The numbers 1-9 have to be in each bix, row and column. So if you have one with 8 numbers, you can work out the last one. And you can see where a number goes in a box if it's in that row or column, you can't put it in that row or column in the box.
Real sudoku puzzles require one solution to be complete. Most sudoku websites use an algorithm to create those one solution sudoku puzzles. You just can't fill an empty grid with random numbers because you can end up with multiple solutions. Here is a list of sudoku websites where you can play online or print sudoku puzzles : http://www.domo-sudoku.com http://www.websudoku.com http://www.sudoku.com http://www.dailysudoku.co.uk yes, but (like I was looking for) you cannot print your OWN puzzles!
In a nonlinear equation, each variable must only have one solution.
The main rules of the number game Sudoku is the have one of every number in each line up , down and in each block. You can not have the same of any number in the same area on the board.
The goal of a Sudoku puzzle is to have one of each numbers 1-9 in each row, column, and 9 x 9 box on the grid. There are other variations but this is the most common setup.
