1,tìm x:
a,\(\dfrac{3}{4}-|2x+1|=\dfrac{7}{8}\)
b,\(2.|2x-3|=\dfrac{1}{2}\)
c,\(7,5-3.|5-2x|=-4,5\)
d,\(|x+\dfrac{4}{15}|-|-3,75|=-|-2,15|\)
giúp mình nha mọi người
\(-\left|-2,15\right|\)
a)|-x+2/5|+1/2=3,5 b)21/5+3:|x/4-2/3|=6
c)7,5-3|5-2x|=-4,5 d)1/3-|5/4-2x|=1/4
e)21/5+3:|x/4-2/3|=6
a)|-x+2/5|+1/2=3,5 b)21/5+3:|x/4-2/3|=6
c)7,5-3|5-2x|=-4,5 d)1/3-|5/4-2x|=1/4
e)21/5+3:|x/4-2/3|=6
a) |x-1/3|=11/5 b)2|2x-3|=1/2
c)2|3x-1|+1=5 d)3/2+4/5|x-3/4|=7/4
e)|2x-5|=4 f)|x/2-1|=3
Mn ơi, giúp mk vs. Mk cần nó lắm.
a) 6 - |\(1/2\)-x|= 2/5
b) |x+3/5|-1/2=1/2
c)4-|x-1/5|=-1/2
d)|x-2/5|+3/4=11/4
a) (2x-4)x+1=(2x-4)x+5
b) (x-3)x+4=(x-3)x+5
c) |x-1|>2
d)| 3+2x|< hoặc= 5
tìm x
Tìm x , biết :
1, |\(\dfrac{3}{2}\)x + \(\dfrac{1}{2}\)| = | 4x - 1 |
2, | \(\dfrac{5}{4}\)x - \(\dfrac{7}{2}\) | - | \(\dfrac{5}{8}x+\dfrac{3}{5}\) | = 0
3, | \(\dfrac{7}{5}x+\dfrac{2}{3}\) | = | \(\dfrac{4}{3}x-\dfrac{1}{4}\) |
4, | \(\dfrac{7}{8}x+\dfrac{5}{6}\) | - | \(\dfrac{1}{2}x+5\) | = 0
Tìm x, biết
a, | x - 5 | + 5 = x
b, | x + 7 | - x = 7
c, | 3x - 4 | + 4 = 3x
d, |7 - 2x | + 7 = 2x
