\(\frac{10}{3}.x-\frac{27}{4}=\frac{13}{4}\)
\(\frac{10}{3}.x=\frac{13}{4}+\frac{27}{4}\)
\(\frac{10}{3}.x=10\)
\(x=10:\frac{10}{3}\)

6. 27/35 x 5/9 - 2/7 x -7/5
7. 10/13 x 13/5 + {-9/5} x 10/3
8. 100/27 x 9/20 + 40% x 5/3
9. 1,5 x 5/12 + 1/4 x 3/4
Tìm x biết
a, 53.(3x + 2 ) :13 = 103:(135: 134)
b, 92.4 - 27 = (x + 350) : x +315
Tìm x biết:
a) ( 19x + 2 . 5^2 ) : 14 = ( 13 - 8 )^2 - 4^2
b)2 . 3^x = 10 . 3^12 + 8 . 27^4

1) 5 – (10 – x) = 7
2) - 32 - (x – 5) = 0
3) -12 + (2x – 9) + x= 0
4) 11 + (15 - x) = 1
5) 4 - (27 - 3) = x - (13 - 4)
6) 8 - (x - 10) = 23 - (- 4 +12)
7) 105 – 5(10 – 5x) = -20
8) (x -1)(8-2x)(3x+123) = 0
9) (x2 - 25)(x+ 10) = 0
10) x(x2+5) = 0
Tìm x biết: a) x + \(\dfrac{2}{3}=\dfrac{4}{27}\) b) \(\dfrac{3}{4}x-\dfrac{7}{3}=\dfrac{1}{4}x+\dfrac{1}{6}\)
c) \(\dfrac{13}{10}x-\dfrac{5}{2}=\dfrac{7}{2}\) d) (3\(x\) + 2) \(\left(\dfrac{-2}{5}x-7\right)=0\)
4-(27-3)=x-(13-4)
