Hello, I need help with this problem. The answer is inside the box but I don't understand how to get the answer. I do understand how to get y, but I got lost on the dy/dx part. The topic is Implicit Differentiation.

For problems 1 & 2, solve each equation for y to express y as an explicit function of x. Then find dy dx 1. yx + 2x = 6 6 - 2x dy -2 y = for x * 0; -6x dx 2. 3x + 12xy + 4y = 0 3x 1 dy -3 y = for x * - 12x + 4 3' dx 4(3x + 1)2
