and also:
is the system consistent, inconsistent, or neither?
is the system dependent, independent, or neither?
is the solution a line, a point, a plane, or is there no solution?

Hard to do matrices here, but if we enclose each row in braces, we have
{{2,5},{3,4}}*{{x},{y}} = {{19},{11}}
so x = -3, y = 5
{{2,5},{3,4}}*{{x},{y}} = {{19},{11}}
so x = -3, y = 5
