By definition, there cannot be a simultaneous equation that cannot be solved, there must be a set of simultaneous equations. It is important to realise that simultaneous equations need not be linear.
It is simple to devise a pair of linear equations that are inconsistent:
x + y = 1 and x + y = 2
There is no solution. Graphically, the two lines are parallel.
Another possibility is
x + y = 1 and 2x + 2y = 2
In this case there are an infinite number of solutions. Graphically, the two lines are coincidet, so that every point on the common line is a solution. There is, therefore, no unique solution.
Yet another situation can arise when the domain of the equations is restricted.
For example,
x2 + y2 = -1 where x and y are real along with any other equation in x and y.

Is it true or false that when using substitution is it best to start by solving the second equation for x?
If it's a simultaneous equation in x and y variables then x or y may be solved before substitution.
What is 5x plus 2y equals -18 2x-3y equals -11?
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
What is 2x plus 3y equals 17 and 3x minus 2y equals 0.5?
It is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13
What is the present perfect tense of solve?
The present perfect forms are have solved and has solved.Examples:They have solved the equation. (plural subject)He has solved the equation. (singular subject)
What is the simultaneous equation for 2x plus 5y equals 20?
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
What are the disadvantages of math equation?
sometimes they just cant be solved without a calculator
Is it true or false that when using substitution is it best to start by solving the second equation for x?
If it's a simultaneous equation in x and y variables then x or y may be solved before substitution.
Y plus 4 equals 4x-2?
That equation cannot be solved since there are 2 unknown in the equation (x and y) but only 1 equation. The number of unknowns must be equal to the number of equations (for simultaneous equations)
What is 5x plus 2y equals -18 2x-3y equals -11?
It's a simultaneous equation and can be solved by elimination which works out as:- x = -4 and y = 1
What is 2x plus 3y equals 17 and 3x minus 2y equals 0.5?
It is a simultaneous equation and when solved its solutions are x = 71/26 and y = 50/13
What is the name of a mathematics equation with two equations?
A simultaneous equation
What is the Answer for 4x plus y equals 2 3x-3y equals -9?
x = -1/5 and y = 14/5 Solved by forming a simultaneous equation and eliminating y.
Can you help me with this simultaneous equation 2x y4 y2x²-x 3?
No because it's not a simultaneous equation but some kind of algebraic expression
Simultaneous equation 2x-2y equals 10?
Simultaneous suggests at least two equations.
What is the present perfect tense of solve?
The present perfect forms are have solved and has solved.Examples:They have solved the equation. (plural subject)He has solved the equation. (singular subject)
What is the simultaneous equation for 2x plus 5y equals 20?
Another straight line equation is needed such that both simultaneous equations will intersect at one point.
What is Simultaneous Equations?
Simultaneous equation is nothing: it cannot exist.A system of simultaneous equations is a set of 2 or more equations with a number of variables. A solution to the system is a set of values for the variables such that when the variables are replaced by these values, each one of the equations is true.The equations may be linear or of any mathematical form. There may by none, one or more - including infinitely many - solutions to a system of simultaneous equations.
