Where they all intersect.
simultaneous equations
It is a set of equations, which is also called a system of equations. There may be no solution, a single (unique) solution or more than one - including infinitely many.
a1/a2 is not equal to b1/b2
Then it has (not have!) a unique solution.
You don't need ANY factor. To find a unique solution, or a few, you would usually need to have as many equations as you have variables.
A single equation is several unknowns will rarely have a unique solution. A system of n equations in n unknown variables may have a unique solution.
simultaneous equations
This is the case when there is only one set of values for each of the variables that satisfies the system of linear equations. It requires the matrix of coefficients. A to be invertible. If the system of equations is y = Ax then the unique solution is x = A-1y.
In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution.
Cramer's rule is applied to obtain the solution when a system of n linear equations in n variables has a unique solution.
Cells that make up the glandular system unique to nematodes. Functions in secretion and excretory systems.
It is not possible to tell. The lines could intersect, in pairs, at several different points giving no solution. A much less likely outcome is that they all intersect at a single point: the unique solution to the system.
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)
False, think of each linear equation as the graph of the line. Then the unique solution (one solution) would be the intersection of the two lines.
It is a set of equations, which is also called a system of equations. There may be no solution, a single (unique) solution or more than one - including infinitely many.
a1/a2 is not equal to b1/b2
Every operating system is unique to the person who is using it!
