\(\text{a, (x - 1)^2 = 1}\\ x-1=1\\ x=2\)
Tìm x:
a) \(x-\dfrac{2}{3}=\dfrac{3}{5}-\dfrac{1}{4}\)
b) \(-\dfrac{2}{3}.x+\dfrac{1}{5}=\dfrac{1}{10}\)
Tìm x:
a, \(\left(12-12\dfrac{1}{3}\right):x+\dfrac{1}{6}=\dfrac{-2}{3}\)
b, \(\dfrac{4}{x}=\dfrac{x}{16}\)
Tìm x:
a) 2/5 = 3/4 : x = -1/2
b) 5/7 - 2/3 . x = 4/5
c) 1/2x + 3/5x = -2/3
d) 4/7x - x = -9/14
2. Tìm x:
a) 4/5 + x = 2/3
b) 1/2 - x = 7/12
c) 3 và 1/2 : x = -7/2
d) 3/8 - 1/6 x =5/2
e) x + 50%x = -1,5
Tìm x:
a,50%x - 0,2 + x =4/5
b,(x - 3/4) : 1/2 + 3/2 =25/2
Giúp mình với!! mình cần gấp!! Cảm ơn
Tìm x:
a) 2x - 2/3 = -3/4
b) x : 3/4 + 1/4 = -2/3
c) 1/4x + 2/5 = 7/5
d) /x//5 - 2 = -3/5
MÌNH CẦN GẤP. CẢM ƠN Ạ
Tìm x:
a, \(x-\dfrac{1}{4}=\dfrac{7}{2}.\dfrac{-3}{5}\)
b, \(\dfrac{x}{134}=\dfrac{9}{7}.\dfrac{5}{-11}\)
Tìm x:
a) \(\dfrac{-x}{4}=\dfrac{-9}{x}\)
b) \(\dfrac{5}{9}+\dfrac{x}{-1}=\dfrac{-1}{3}\)
c) \(x:3\dfrac{1}{15}=1\dfrac{1}{2}\)
d) \(\dfrac{3x-1}{-5}=\dfrac{-5}{3x-1}\)
Tìm x:a,42-42(x+1)=0. b ,(2x+4)-(x+3)=0
