What are the THREE steps needed in solving a system of simultaneous equations using Row Operations?

Re: Simultaneous Equations

What are the THREE steps needed in solving a system of simultaneous equations using Row Operations?

There are many different steps one might take. From the form of the question, your book is asking you to repeat whatever were the three steps presented by your book in the section on row operations. So open your book to that section, and copy down the steps.

There are 2 ways of solving simultaneous equations - the graphical method and the elimination method. With the graphical method you would draw graphs for the equation and the answer would be the point at which they intercept. With the elimination method you would label the equations 1 and 2 and then make the coefficient of either x or y the same so that you can find out one of the values. You would then substitute the value you've just found so that you can find the other value.

ok

Thank you girl in black.

Actually, there are many ways: Gaussian elimination, Gauss-Jordan elimination, matrix row operations, Cramer's Rule, substitution, addition, graphing (for some specialized cases), and so forth.

And each method has its own steps. Only the original poster knows "the three steps" listed in his book in its particular presentation of the row-operation method. To get the answer right on his test, he'll need to look that up.
