Ta có:
\(\left(x-6\right)\left(7-x\right)=0\Rightarrow\hept{\begin{cases}x-6=0\\7-x=0\end{cases}}\Rightarrow\hept{\begin{cases}x=6\\x=7\end{cases}}.\)
Vậy x=6 hoặc x=7, giải chi tiết rồi nhé!
Tim cac so nguyen x thoa man (x-7)(x+3) nho hon 0
Tim so nguyen x, biet :
a/ -24 + (x + 4)^4 = 10^3
b/ 2.(x + 7) - 3.(6 - x) = -24
c/ 3x - 6x^2 = 0
Tim so nguyen x , biet:
|x+7|-x-7=0
tim so nguyen x thỏa mãn x-6<0 va 3-x<0
bai 1 tim so nguyen duong nho nhat co 3 chu so , so nguyen a lon nhat co 2 chu so
bai 2: tim x thuoc Z biet
a, / x/ = -5
b, /x/= <7
c, /x/ = 4
d, /x/=0
tim so nguyen x a)2-x=5-6 b)7-x=17-(-5) c)|x+3|=7 d)x-(17-x)=x-7 e)(x-2).(5-x)=0
tim so nguyen x/3 - 4/y = 7/6
tim cap so nguyen x,y biet
x^2-xy-y+7=0
tim cac so nguyen x ybiet
|x-2|+|x.y-6|=0
