若|2x+2y-5|与(2x-5y-16)²互为相反数,求y的x次方,
若|2x+2y-5|与(2x-5y-16)²互为相反数,求y的x次方,
若|2x+2y-5|与(2x-5y-16)²互为相反数,求y的x次方,
若|2x+2y-5|与(2x-5y-16)²互为相反数,
则|2x+2y-5|=0,(2x-5y-16)²=0
2x+2y-5=0,①
2x-5y-16=0 ②
①-②得:
7y=21
y=3
将y=3代入①得:
2x+6-5=0
x=-1/2
所以x=-1/2,y=3
很高兴为您解答,【学习宝典】团队为您答题.

很简单的,因为|2x+2y-5|与(2x-5y-16)²互为相反数
所以 |2x+2y-5|+(2x-5y-16)²=0
解连立方程组
2x+2y-5=0
2x-5y-16=0
可求X,Y的值
剩下的不用我说了吧。
还有,题目是否抄错了,你这个题目解出来x=57/14,y=-(11/7)
是否应该是2x-5y+16
若|x-y-5|与|2x+3y-15|互为相反数,则x+y=?
若|2x+2y-5|与(2x-5y-16)²互为相反数,求y的x次方,
1.20y(2y-x)²与5x(x-2y)平方的公因式是—— 2.分解因式(x+y)(x-y)-(x+y)²
若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值
若2│X-Y+5│与(x+y-13)平方互为相反数求X与Y
5x(x-y)+2y(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)
(X+2Y)(5X-2Y)
(x+2y)(5x-2y)
4x+2y-5x-y
(2x-3y)-(5x-y)
(2X-3y)-(5x-y)
(x-y)^2+5(x-y)-14
(2x-5y)(3x+y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
