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

What is the Cauchy Kovalevskaya theorem?
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.
Is it possible to solve systems of equations?
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.
Are Linear equation systems consistent or inconsistent?
It depends on the equations.
What jobs use systems of equations?
i need to do this for math class
Why do you solve systems of equations?
because you need maths in your life.. everyone does
When is it best to solve a systems of linear equations using elimination?
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.
What can systems of equations be solved by?
By elimination or substitution
What is the use of gaussian elimination in education world situations?
Gaussian elimination is used to solve systems of linear equations.
How do you solve systems of equations by using elimination?
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
Solve linear equations with complex coefficients on both sides?
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.
Why is substitution the best method in solving systems of equations?
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

How can you use a graph to solve systems of equations?
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
What is the classification of a system of equations?
The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
Which is more efficient for solving linear systems gaussian elimination or cramer's rule?
Of course, Gaussian Elimination!
Solve the following systems of simultaneous linear equations using Gauss elimination method and Gauss-Seidel Method?
