Q: Which metal reacts with oxygen to form a basic oxide?
Did You Know?
Divide second equation by 2: \(x + y = 6\). Compare with first equation: \(x + y = 5\). We have \(x + y = 5\) and \(x + y = 6\), which is impossible. Therefore, no solution exists. Graphically, these are parallel lines that never intersect.
