若x/2=y/3,且x+y=10,则x=?y=?

若x/2=y/3,且x+y=10,则x=?y=? 若|x|=2,|y|=3,且y/2+x《0则x+y 若x、y互为相反数,且2x-3y=5,则x+y=? (x+y)(x+y-10)+25=0,且x-y=3,求x,y (x+y)(x+y-10)+25=0,且x-y=3,求x,y 若2x-3y= -10,且x,y互为相反数,则(x+1(y-3)得多少? ·若x.y互为相反数,且（x+y+3)(x-y-2)=6,则x等于几 若x:y=2:3,且3x+2y=60,则x= 若|x|=3,|y|=2,且x＞y,求x+y的值. |x|=3,|Y|=2,且x>Y,则x+y的值为多少? |x|=3,|Y|=2,且x>Y,则x+y的值为多少 ：已知x与y互为相反数,且2x-y=3,则x-y= 若x,y为正整数,且满足3x(x+y)-y(x+y)=7,求x,y 若｜x｜=3,｜y｜=2,且｜x－y｜=y－x,求x+y的值. 若|x|=3,|y|=2,且|x-y|=y-x,求x+y的值 若|x|=3,|y|=2,且|x-y|=y-x,求x+y的值 若X,Y互为相反数,且(X+Y+3)(X-Y-2)=0,求X,Y的值? 若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
