tim so nguyen x biet \(\left|18-2.\right|-x+5=12\)
tim so nguyen x: -28-7.\(\left|-3x+15\right|\)=-70
tim x,y biet: (x-2).(y+3) = 7
(x+3).(y+5)= -6
y+3 chia het cho x+1
2.x+(-5) chia het cho x+4
giup mik vs mik cam on a:))))
tim x:

|5-2.x|=7 (tim x)
Mn giúp mk vs:
Tìm x, bt:
a.(x-2)(x+3)>0
b.(x-2)(x-1)>0
c.(x-2)(x^2+1)>0
d.(x-1)(x+2)>0
Tìm x,y thỏa mãn:
a.x(y+3)=3
b.(x-1)(y+2)=-3
c.x+3chia hết cho x+1
d.2x+3 chia hết cho x+1
a) x ( x + 0 ) = 0
b) ( x - 1 ) ( 7 - x ) = 0
c) ( -x + 5 ) ( 3 - x ) = 0
d) ( x + 5 ) + ( x - 9 ) = 13
e) ( 4 + x ) + ( x - 7 ) = x + 2
f) ( 3x + 5 ) - ( 2x - 7) = 4 - x
g) ( x - 1 )2 = 36
h) ( 3 - x ) 3 = -27
