方程和英语问题
(k-2)*(k-2)+kx-5=0是一元一次方程.则k=___,
Today is September 10th.It is T___ day.(是填Teacher )
Iwrite down the w___,"Thank you,teacher!"
I think my teacher will be very h__ to see my presents.
方程和英语问题(k-2)*(k-2)+kx-5=0是一元一次方程.则k=___,Today is September 10th.It is T___ day.(是填Teacher )Iwrite down the w___,"Thank you,teacher!"I think my teacher will be very h__ to see my presents.
因为(k-2)*(k-2)+kx-5=0是一元一次方程,
所以(K-2)*(K-2)=0,
K=2.KX-5=0
X=2.5

应该是Teachers' words happy
由原式==>k^2-4k+4+kx-5=0
==>k^2+(k-4)x-1=0
因为没有指定k,x哪个是未知数,只能视为2个都是未知数 ,1元一次==>x=-k
==>4k-1=0 k=0.25 x=-0.25
