(4x+y)+3(4x+y)-4=0,则4x+y值为()(4x+y)+3(4x+y)-4=0,则4x+y值为()(4x+y)+3(4x+y)-4=0,则4x+y值为()(4x+y)+3(4x+y)-4

(4x+y)+3(4x+y)-4=0,则4x+y值为( )
(4x+y)+3(4x+y)-4=0,则4x+y值为( )

(4x+y)+3(4x+y)-4=0,则4x+y值为( )
(4x+y)+3(4x+y)-4=0
则[(4x+y)+4]*[(4x+y)-1]=0
那么,(4x+y)+4=0 (4x+y)-1=0
4x+y=-4 或者 4x+y=1
所以,4x+y值为(-4或者1)

1或者-4

(4x+y)2+3(4x+y)-4=0
﹙4x+y+4)(4x+y-1)=0
4x+y=-4或4x+y=1
满意请采纳。

1

4(4x+y)=4
4x+y=1

-4或者是1用十字相乘法

-4,1

你设4x+y为x,然后用十字相乘法(x+4)* (x-1)
