Suppose x and y are real numbers and 3x+2y≤5. Prove that if x>1 then y<1
The discussion centers on the mathematical proof that if \( x > 1 \) and \( 3x + 2y \leq 5 \), then it follows that \( y < 1 \). The participants explore the implications of assuming both \( x > 1 \) and \( y \geq 1 \) simultaneously, leading to a contradiction with the given inequality. The conclusion is that the assumption cannot hold true, thereby validating the original statement.
