### How do you solve x minus y equals 6 and x plus y equals -2?

There are several methods for solving simultaneous equations. In
this case, you can simply add the two equations together. This will
eliminate one of the variables (the "y"), so you can solve a single
equation with one variable (variable "x"). Once you solve for "x",
replace it in one of the original equations, and solve for "y".

Unfortunately, limitations of the browser used by Answers.com
means that we cannot see most symbols. It is therefore impossible
to give a proper answer to your question. Please resubmit your
question spelling out the symbols as "plus", "minus", "equals" etc.
Also use ^ to indicate powers (eg x-squared = x^2).
As a consequence of the site issues, there is no equation,
simply some random expressions. Equations can be solved, random
expressions ... nope!
