TA CÓ : 3x+3x+3x=174 => 9x=174 => x= 174/9= 19,1
Vậy x = 19,1
tim x
2/3x(1/2+3/4-1/3)<x/18<7/3x(1/2-1/6)
Tim x:
a) (3x-1)(-1/2x+5)=0
b) 2/3x+1/2x=5/2
tim stn x y biết ( 6x + 5y + 1). ( 6x + y + 3x2 + 3x ) = 105
Tim X,y thuộc Z
(X-3).(2x+1)=7
(2x+1).(3x-2)=-55
Xy+3x-7y=21
tim x a,1/3x-4/3=5 b,2/3x+1/2=2 c,3-3/4x=x-5
Tim x biet 3x + 17 chia het cho 3x + 1
tim x biet |2-3x|=x-1
tim số nguyên x biết
5/6 = x -1/x
1/2 = x +1/3x
2x -1/3=3x +1/4
4/3=2x-1/x
Tim x :(2x-3-4x):(5-3x-6)=2.(7-3x-5)
