Tell whether the ordered pair (5, -5) is a solution of the system
Y=5
That depends is it 3x + or - 9?
Assuming that you meant that the equation is y=3x+1, the slope is 3. This is because the equation of any line in the form of y=mx+b has a slope of "m". Therefore, the value of m in this equation is 3.
This equation is incomplete, and to solve for two variables, you need two equations. So there is no "answer" for this.
Without any equality signs the given expressions can't be considered to be equations.
Neither y3x-3 nor 3x-y3 are equations, and so neither of them can have a solution. 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. And using ^ to indicate powers (eg x-squared = x^2).
Without any equality signs the given terms can't be considered to be equations and so therefore there are no solutions.
x + y = 82x - y = 5-------------------- add together to eliminate y3x = 13x = 13/3Substitute for x in one of the original equations:(13/3) + y = 8y = 24/3 - 13/3y = 11/3x=13/3 & y=11/3
