I will give a simple example just to illustrate the idea, but all you have to do is multiply any of the equations by a constant to make them inversely additive values and add the equations.
.2x-.5y = 10
.5x+.3y = 15
.2 = 1/5 and .5 = 1/2 so if I multiply the first equation by -5 and the second by 2, we get the system:
-x+2.5y = -50
x+.6y = 30
(-x+2.5y = -50) + (x+.6y = 30) = (3.1y = -20)
Solving for the variables, we get y = -6.452 and x = 33.871
The Cauchy kovalevskaya theorem tells us about solutions to systems of differential equations. If we look at m equations in n dimension, with coefficient that are analytic function, we can know about the existence of solutions using this theorem.
very possible, unless there is something preventing them from being true, like an undefined answer. The most common ways are through substitution, graphing, and elimination.
It depends on the equations.
i need to do this for math class
because you need maths in your life.. everyone does
Elimination is particularly easy when one of the coefficients is one, or the equation can be divided by a number to reduce a coefficient to one. This makes substitution and elimination more trivial.
By elimination or substitution
Gaussian elimination is used to solve systems of linear equations.
Multiply every term in both equations by any number that is not 0 or 1, and has not been posted in our discussion already. Then solve the new system you have created using elimination or substitution method:6x + 9y = -310x - 6y = 58
An algebraic model used to find the exact solution of a system of equations is typically represented by matrices and can be solved using methods such as Gaussian elimination or matrix inversion. In this context, systems of linear equations can be expressed in matrix form as (AX = B), where (A) is the coefficient matrix, (X) is the variable matrix, and (B) is the constant matrix. By applying these methods, one can systematically determine the values of the variables that satisfy all equations in the system. Additionally, tools like the determinant and Cramer's Rule can also be employed for certain types of systems.
To solve a system of two equations, you can use one of three methods: substitution, elimination, or graphing. In the substitution method, you solve one equation for one variable and substitute that expression into the other equation. In the elimination method, you manipulate the equations to eliminate one variable by adding or subtracting them. Graphing involves plotting both equations on a graph and identifying their point of intersection, which represents the solution.
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
There are several methods to solve linear equations, including the substitution method, elimination method, and graphical method. Additionally, matrix methods such as Gaussian elimination and using inverse matrices can also be employed for solving systems of linear equations. Each method has its own advantages depending on the complexity of the equations and the number of variables involved.
It is not always the best method, sometimes elimination is the way you should solve systems. It is best to use substitution when you havea variable isolated on one side

The addition method is sometimes referred to as the "elimination method." This technique is used in solving systems of linear equations by adding or subtracting the equations to eliminate one variable, making it easier to solve for the other variable.
