已知y1=-2x+3,y2=3x-2(1)当x取何值时,y1=y2?(2)当x取何值时,y1比y2小5?已知y1=-2x+3,y2=3x-2(1)当x取何值时,y1=y2?(2)当x取何值时,y1比y

已知y1=-2x+3,y2=3x-2(1)当x取何值时,y1=y2?(2)当x取何值时,y1比y2小5?
已知y1=-2x+3,y2=3x-2
(1)当x取何值时,y1=y2?
(2)当x取何值时,y1比y2小5?

已知y1=-2x+3,y2=3x-2(1)当x取何值时,y1=y2?(2)当x取何值时,y1比y2小5?
(1)-2x+3=3x-2
-5x=-5
x=1
(2)y2-y1=5
3x-2+2X-3=5
x=2
