Question

Please can someone tell me whether my answer to the question is right? The topic is simultaneous equations.

Answer 1

You can easily check your own solutions to simultaneous equation problems.  You've found values for x and y.  Choose either of the original two equations and substitute these x- and y-values into it.  Is the resulting equation then true?  If so, you have a solution.  If not, you don't.

Answer 2

X should equal -13.33. Y is correct, 13.33
