若|2x+3y-6|与(3x-4y-25)2互为相反数则满足条件的x=?y=?

x+y/2+x-y/3=6,4(x+y)-3(x-y)=-20 {(x+y)/2+(x-y)/3=6 4(x+y)-3(x-y)=-20 4(x+y)-3(x-y)=-20,2/x+y+3/x-y=6 若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于 {3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1 81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2 4x-3y/x-2y÷6y-8x/y-2x （x+y）/2- x-y/2=6 3(x+y)=4(x-y) x+y/3+x-y/2=6 4(x+y)-2(x-y)=40 （y-x）^4（x-y）^3+2（x-y）^6（y-x） 若|2x+3y-6|与(3x-4y-25)2互为相反数则满足条件的x=?y=? 若5x+3y=3x+4y=x+2y+6,则x+y=___ 若|x+3|与|2y-3|互为相反数,求x+y:x-y的值如题 5x-6y= -28 ,3x+4y=6求x与y 通分4x²-y² 分之y与3y-6x分之x 若｜x-y-5｜与｜2x+3y-15｜互为相反数,则x+y＝? 若／X+Y-9／+（2X-Y+3)=0求X与Y的值 3x+y+5与2-4y+2x是同类项,求x,y
