化简求值 当(x-3/16)²+|y+3/17|=0时,求[(y-2x)·（-2x-y)-4(x-2y)²]÷3y的值
化简求值 当(x-3/16)²+|y+3/17|=0时,求[(y-2x)·（-2x-y)-4(x-2y)²]÷3y的值
化简求值 当(x-3/16)²+|y+3/17|=0时,求[(y-2x)·（-2x-y)-4(x-2y)²]÷3y的值
(x-3/16)²+|y+3/17|=0
所以x-3/16=y+3/17=0
x=3/16,y=-3/17
所以原式=(4x²-y²-4x²+16xy-16y²)÷3y
=(16xy-17y²)÷3y
=16x/3-17y/3
=1+1
=2
