若|3x+2y-5|与(2x-5y-16)²互为相反数,求y的x次方的值.

若｜x-y-5｜与｜2x+3y-15｜互为相反数,则x+y＝? 化简:5(x-y)+2(x+y)-3(x-y) (3x+2y)+(5x-y)i=17-2i.求x与y 3x+y+5与2-4y+2x是同类项,求x,y 已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y) (2x-3y)-(5x-y) (2X-3y)-(5x-y) (2x-5y)(3x+y) 因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+（x-3y)(x-5y)+(x-2y)(x-4y) (2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解 若|2x+2y-5|与(2x-5y-16)²互为相反数,求y的x次方, [2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2 若(x+5y-13)^2与|2x+3y-12|互为相反数,求x、y的值. 若|x+2y-5|与（3x-y-1）的2次方互为相反数,则x+y= 若(2x+y-4与(3x-5y-12)的绝对值互为相反数,则x+y= 若（2x+y-4)²与|3x-5y-12|互为相反数,则x+y=___ 若(x+y-5)²与|3y-2x+10|互为相反数,则x,y=? 若x-y/x+y=5,求x-y/2x+2y+5x+5y/3x-3y的值
