One method is to use Gaussian elimination. This involves adding or subtracting equations in order to create either all zeroes in a column below the leading entry of a row, or a leading entry in a column with only zeroes below it. This process is continued until the system is in what is called reduced row echelon form. Once the system is in this form, the solution is easily

I am looking for a math tutor for my 6th grade son. He is currently taking Pre-Algebra and is having some difficulty. I would like someone who is patient and able to explain concepts in a way that he can understand. We are looking for someone to meet with him once a week for an hour.

Review In mathematics, substitution is a method for solving equations in which one variable is replaced with an expression in terms of other variables. The expression obtained after substituting the variable is then solved for the other variable. For example, in the equation `x + 3 = 5`, one could substitute `x` with `5 - 3` to obtain `5 - 3 + 3 = 5`, which simplifies to `5 = 5`. From this, we can see that `x = 2
