y1=X+3 y2=2-x当x取几时y1=y2?当x取几是y1比y2大5?

y1=X+3 y2=2-x当x取几时y1=y2?当x取几是y1比y2大5? 已知y1=3x-2,y2=3+2x.当x取何值时,y1=y2? 已知：y1=3x-2,y2=3+2x.当x取何值时,y1=y2 已知Y1=3X+2 Y2=-2X+4当X取何值时.Y1大于Y2 已知Y1=X-2,Y2=-3X+10,当X= 时,Y1=Y2;当X= 时,Y1>Y2;当X= 时,Y1 已知一次函数y1=-x+3与y2=3x-1,当x取何值时,y1>y2?y1=y2?y1 一次函数y1=2x+1,y2=5x+16,当x分别取何值时,y1=y2,y1>y2,y1 已知y1=3分之2x+1,y2=6分之10x+1,当x=几时,y1与y2的差是1. 若Y1=2X+3,y2=3x-1,当x取何值时,y1 已知y1=loga(x-1),y2=log(3-2x)求当x取何值时有y1 已知y1=2x+8 y2=6-2x 当x取何值时,y1=y2 当x取何值时,y2-y1=5已知y1=2x+8 y2=6-2x 当x取何值时,y1=y2 当x取何值时,y2-y1=5 若Y1=-X+3,Y2=3X-4 ,试确定当X取何值时：(1)Y1小于Y2 (2)Y1等于Y2 (3)Y1大于Y2 已知函数y1=-2x-3 y2=-5x用图象法,当x取值满足什么条件时 y1>y2 y1=y2 y1<y2 y1=-x+3,y2=3x-4,当x取何值时y1=y2? 已知y1=2x+8,y2=6-2x.当x取何值时,y1=y2? 已知y1=-x+3,y2=3x-4,当x取何值时,y1＜y2?急、 已知函数y1=x+1和y2=-2x+3,当x...时,y1 已知y1=3（5/3x-1/2),y2=4(1/2-x当想取何值时,y1=y2已知y1=3（5/3x-1/2),y2=4(1/2-x）当x取何值时,y1=y2当x取何值时,y1比y2大4?最好有想法！
