How do you find the solution to the system of equations on ti- 89 calculator?

Can substitution in math be used to find the exact solution of a system of equations?

yes

How do you check a solution to a system of equations?

Put the values that you find (as the solution) back into one (or more) of the original equations and evaluate them. If they remain true then the solution checks out. If one equation does not contain all the variables involved in the system, you may have to repeat with another of the original equations.

When solving a system of equations by elimination you find what?

You find a solution set. Depending on whether the equations are linear or otherwise, consistent or not, the solution set may consist of none, one, several or infinitely many possible solutions to the system.

How do you find the solution to system of equations?

Parenthesis, exponents, multiplication, division, addition, subtraction. PEMDAS

When we look for a solution for a system of equations or inequalities are we looking into an AND situation or an OR situation?

Unless otherwise stated, the "AND" case is normally assumed, i.e., you have to find a solution that satisfies ALL equations.

What is the purpose of Cramer's rule?

In math, the purpose of Cramer's rule is to be able to find the solution of a system of linear equations by using determinants and matrices. Cramer's rule makes it easy to find a system of equations that have many unknown variables.

What is a solution to the following system of equations using substitution -5x plus y equals -5?

-10

What are multi step equations?

They are equations that involve many steps to find the solution.

When you formulate a system of equations you have at least how many factors?

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.

What is the situation when two linear inequalities have no common solution?

To solve a system means to find the x- and y-values for which both of the equations are true. Systems of linear equations can be solved using a variety of methods. One method is to graph the equations as two lines and examine them. If the lines intersect at exactly one point, there is one solution to the system, and the system is called consistent. If the two lines are on top of one another, there are an infinite number of solutions, because each point on the line is considered a solution (this system is called dependent). If the two lines are parallel, there is no solution (this system is called inconsistent). To solve a system means to find the x- and y-values for which both of the equations are true.

How do you use a graphing calculator to solve quadratic equations?

Graph the equation then find the x intercepts.

How can you find solutions for equations with two variables?

if you can, you could always search a online calculator and use that.
