9th Grade Math: Systems Of Equations
In mathematics system of equations are a set of equations containing multiple variables. To solve system of equations, the solver needs to use the provided equations to find the exact value of each variable. Generally the solver uses either a graphical method (by plotting all the lines and/or curves on the same graph and finding the exact coordinates of their intersection), the matrix method, the substitution method, and/or the elimination method. Some textbooks refer to the elimination method as the addition method, since it involves adding equations (or constant multiples of the said equations) to one another.

Tutoring my 9th grade son.
I teach math to 9th grade -12th grade at a small city school in North Carolina. Knowing that each student in NC has to score levels 3 or 4 on the EOC Algebra 1 test to graduate, any real-life application type problems would be beneficial to the success of my students. Knowing also that matrces are heavily tested on the NC EOC test, this website appears that it would be helpful. Our textbooks do not offer many examples of matrices . Thank you.
