Good evening Candice! Two linear simultaneous equations in two variables will have exactly one solution in the great majority of situations. We can always check back our values of x and y into the equations to see if they are valid. The given solution is valid for the first equation but fails in the second equation.

Good evening Candice! I obtained x = -0.5, y = -1.5 for my workings. I used an ordinary method instead of matrix method as the matrix method of solving simultaneous equations is not in your syllabus for E Maths and A Maths.
