Check whether (2 root 2, 3 root 2) is a solution of 3y-2x = 1 or not The correct answer and explanation is: Let’s check whether the point (22,32)(2\sqrt{2}, 3\sqrt{2}) satisfies the equation 3y−2x=13y – 2x = 1. Given: Step-by-Step Calculation: Substitute x=22x = 2\sqrt{2} and y=32y = 3\sqrt{2} into the equation: 3(32)−2(22)=13(3\sqrt{2}) – 2(2\sqrt{2})
