Tìm x, biết;
a) 25/x+1 – 1/1/6 = -1/3 – 0,5
b) 2,5x + 3/4 = 3,5x
c) (8/7-5/3). 7/2x+6/5. 15/7 = 2/7x
d) |3/2 – 1/3|. -6/7x- 7/5 = 25/7 . 21/5
e) (1/1/3 – 25%x – 5/12) – 3x = 1,6 :3/5
f) (-2/3)^2 : (x-1) + 3^1001 . [7/4 – (3/2^2 + 1)] = 2/9
g) x^2 + 8/9 =41/36
h) (x-3)^2 + -9/25 = 2/5 . 8/5
i) 3/11 . 22/6 – (x-1)^2 = 7/16
k) 1+ (x+1)^3 = 37/64
l) (x – 1/2) ^2 – 9/16 =1
m) (x – 1/2)^2 – 9/16 = 1
v) 3-x/5-x = (-3/5)^2
Mong mn lm hết giúp vs
Đg cần gấp!!!
$a) \dfrac{25}{x+1}+1-\dfrac{1}{\dfrac{1}{6}}=-\dfrac{1}{3}-0,5(ĐK:x\neq -1)\\\Leftrightarrow \dfrac{25}{x+1}+1-6=-\dfrac{1}{3}-\dfrac{1}{2}\\\Leftrightarrow \dfrac{25}{x+1}-5=-\dfrac{5}{6}\\\Leftrightarrow \dfrac{25}{x+1}=-\dfrac{5}{6}+5\\\Leftrightarrow \dfrac{25}{x+1}=\dfrac{25}{6}\\\Leftrightarrow x+1=6\\\Leftrightarrow x=6-1\\\Leftrightarrow x=5$
Vậy $x=5$
