若x-3y=0,且x≠0,2x+5y/3x-y的直是?若x-3y=0,且x≠0,2x+5y/3x-y的直是?若x-3y=0,且x≠0,2x+5y/3x-y的直是?∵x-3y=0,∴x=3y∴(2x+5
若x-3y=0,且x≠0,2x+5y/3x-y的直是?
若x-3y=0,且x≠0,2x+5y/3x-y的直是?
若x-3y=0,且x≠0,2x+5y/3x-y的直是?
∵x-3y=0,∴x=3y
∴(2x+5y)/(3x-y)=(6y+5y)/(9y-y)=(11y)/(8y)=11/8
8/11
11/8
若x-3y=0,且x≠0,2x+5y/3x-y的直是?
已知7x+5y/2y-x=3/2,且x≠0,求X/x-4y
若x>0,y>0,且√x(√x+√y)=3√y(√x+5√y),求2x+2√x*√y+3y/x-√x*√y+y
已知2x-y/7x+5y=2/3且y≠0,求x/y的值
若x^5+x^4y+x^4+x+y+1=0,且3x+2y=1,求x,y的值
若|x|=2,|y|=3,且y/2+x《0则x+y
若3x+5y=0,且y≠0,求x:y的值
若3x+5y=0,且y≠0,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?
已知x²+5xy-6y²=0且y≠0,求值:(1)x/y;(2)2x-3y/3x-2y
(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(3x+2y-10)^0无意义,且2x+y=5,求x、y的值.
若[2x+y-5]^0无意义,且3x+2y=8,求X,Y的值
已知,x>0,y>0,x≠y,且x+y=x^2+y^2+xy,求证:1小于x+y小于4/3
已知x*x-2xy-3y*y=0且x不等于0 y不等于0,那么5x-4y/5x+4y=
2y-x/7x+5y=2/3 且y不等于0 则x/y的值为?
若(2y-x)/(7x+5y)=2/3,且y≠0,则x/y的值等于
