Mọi người ơi giúp mình nhanh nha.

Ai giúp mình thì mình sẽ tick cho.

A. Tìm x:

a) \(\frac{3}{4}\)+\(\frac{1}{4}\): x = -3

b) \(\frac{1}{3}\)+ \(\frac{2}{3}\): x = -7

c) | x - 1 | = 5

d) \(\frac{17}{2}\)- | 2x - \(\frac{3}{4}\)| = \(\frac{-7}{4}\)

g) ( x + \(\frac{1}{2}\)) - ( \(\frac{2}{3}\)- 2x ) = 0

giúp mình nha (. là nhân nhé)

1.thực hiện phép tính

a)(-\(\dfrac{2}{3}\)).\(\dfrac{3}{11}\)-(\(\dfrac{4}{3}\))\(^2\).\(\dfrac{3}{11}\)

b)(-1\(\dfrac{3}{4}\))\(^2\)-(\(\dfrac{1}{2}\))\(^4\)

c)(-\(\dfrac{1}{3}\))\(_7\).3\(^7\)

d)(5-\(\dfrac{1}{5}\)+\(\dfrac{1}{6}\))-(4-\(\dfrac{1}{5}\)+\(\dfrac{5}{6}\))-(3-\(\dfrac{1}{2}\)-\(\dfrac{1}{6}\))

2.tìm x

a)/x+\(\dfrac{3}{4}\)/-\(\dfrac{1}{2}\)=0

b)(x-1)\(^2\)-1=(-2)\(^3\)

c)1-(3-x)\(^3\)=(-13).2

d)(2-x)\(^4\)-17=3\(^2\).(-2)

bài 1 : tính

b, \(\dfrac{7}{12}\) + \(\dfrac{5}{12}\) : 6 - \(\dfrac{11}{36}\)

c, ( \(\dfrac{4}{5}\) +\(\dfrac{1}{2}\) ) : ( \(\dfrac{3}{13}\)-\(\dfrac{8}{13}\))

d, ( \(\dfrac{2}{3}\) -\(\dfrac{1}{4}\) +\(\dfrac{5}{11}\) ) : ( \(\dfrac{8}{12}\) +1 - \(\dfrac{7}{11}\) )

bài 2 , tìm x, biết

a, \(\dfrac{-2}{5}\). x +\(\dfrac{4}{3}\) = \(\dfrac{7}{3}\)

b,\(\dfrac{9}{8}\)+\(\dfrac{3}{8}\)-x = 0,125

c,\(\dfrac{3}{4}\): x =\(\dfrac{-7}{12}\)

d,\(\dfrac{3}{8}\)-\(\dfrac{1}{6}\)- x = \(\dfrac{1}{4}\)

e, \(\dfrac{1}{3}\)+\(\dfrac{1}{2}\): x = -4

1. Tìm x, biết:

a, \(1\dfrac{3}{5}\) + \(\dfrac{\dfrac{2}{7}+\dfrac{2}{17}+\dfrac{2}{37}}{\dfrac{5}{7}+\dfrac{5}{17}+\dfrac{5}{37}}\) . x = \(\dfrac{16}{5}\)

b, (\(\dfrac{1}{24.25}\) + \(\dfrac{1}{25.26}\) + . . . + \(\dfrac{1}{39.40}\) ) . 120 + x. \(\dfrac{1}{3}\) = -4

c, \(\left|x-\dfrac{1}{3}\right|\) . 2 + \(\dfrac{4}{5}\) = 0,24

d, \(\dfrac{24}{7x-3}\) = \(\dfrac{-4}{25}\)

e, ( 50% x + \(5\dfrac{1}{4}\) ) , \(\dfrac{-2}{3}\) = \(2\dfrac{5}{6}\)

f, \(1\dfrac{1}{3}\) - 25%\(\dfrac{-5}{12}\) + 2x = 1,6 : \(\dfrac{3}{5}\)
