\(1-\left(\dfrac{43}{8}+x-\dfrac{173}{24}\right):16\cdot\dfrac{2}{3}=0\)
=>\(\left(x+\dfrac{129}{24}-\dfrac{173}{24}\right):16\cdot\dfrac{2}{3}=1\)
=>\(\left(x-\dfrac{44}{24}\right):16=1:\dfrac{2}{3}=\dfrac{3}{2}\)
=>\(x-\dfrac{11}{6}=16\cdot\dfrac{3}{2}=24\)
=>\(x=24+\dfrac{11}{6}=\dfrac{155}{6}\)
tìm x:

Tìm x:
a, 1/3x+2/5.(x+1)=0
b, 1-(43/8+x-173/24):(-50/3)=0
43/8+x-173/24=-5/3
(43/8+x-173/24):50/3=2
jup mik vs thank
43/8 + x - 173/24 = -46/3
Giúp mk vớiiiiiiii
5. 91/27 - 56/9 : x = 154/7
4. 1 - ( 43/8 + x - 173/24 ) : 50/3 = 0
-8/5 : 4/5 + | x | = 0,125 * ( -4 )| x + 1/3 | * 17/5 - 12/5 = 21/2x - 2/3x = 7/12 + 3/4x
Tìm x biết :
1-(42/8+x-173/24):50/3=0
Tìm x:
a) (3x-12) : 8 + 10 = 13
b) (x + 5).8-20 = 60
c) 3.[ 35 + (x-10) ] - 375 = 0
d) ( 158x+ 173 - 24 ) : 35 = 81
e) x - 140 : 35 =0
