1) Giải các pt sau:
a) \(\frac{x-3}{5}=6-\frac{1-2x}{3}\)
b) \(\frac{3x-2}{6}-5=\frac{3-2\left(x+7\right)}{4}\)
c) \(\frac{x+8}{6}-\frac{2x-5}{5}=\frac{x-1}{3}-x+7\)
d) \(\frac{7x}{8}-5\left(x-9\right)=\frac{2x+1,5}{6}\)
e) \(\frac{5\left(x-1\right)+2}{6}-\frac{7x-1}{4}=\frac{2\left(2x+1\right)}{7}-5\)
f) \(\frac{x+1}{3}+\frac{3\left(2x+1\right)}{4}=\frac{2x+3\left(x+1\right)}{6}+\frac{7+12x}{12}\)
-Giải pt :
A. x(x+3)-(2x-1)(x+3)=0
B. 3x-5(x+2)=3(4-2x)
C. (4x-3)(5x-6)=(4x-3)(2x-3)
A, x/2x+6 - x/2x+2= 3x+2/(x+1)(x+3)
B, 5/x+7+8/2x+14= 2/3
C, x-1/x-1/x+1= 2x-1/x^2+x

3) 5-2x=0
4) 3x-5=7
5) 8-3x=6
6) 8=11x+6
7)-9+2x=0
8) 7x+2=0
9) 5x-6=6+2x
10) 10+2x=3x-7
11) 5x-3=16-8x
12)-7-5x=8+9x
13) 18-5x=7+3x
14) 9-7x=-4x+3
15) 11-11x=21-5x

c x-3+2(x-3)-1/3=3-x/4
ai giúp mik đc câu nào cũng đc ạ
a. 1+2x-5/6 + 3- x/4
b. x+1/2 - x-2/3
c. 2x-1/3 +x =x+4
d. x+5/4 -2x-3/3 -6x-1/8 + 2x-1/12
Mọi người giúp em với đề này khó quá
1) (3x-2)/3-2=(4x+1)/4
2) (x-3)/4+(2x-1)/3=(2-x)/6
3) 1/2 (x+1)+1/4 (x+3)=3-1/3 (x+2)
4) (x+4)/5-x+4=x/3-(x-2)/2
5) (4-5x)/6=2(-x+1)/2
6) (-(x-3))/2-2=5(x+2)/4
7)2(2x+1)/5-(6+x)/3=(5-4x)/15
8) (7-3x)/2-(5+x)/5=1
9)(x-1)/2+3(x+1)/8=(11-5x)/3
10)(3+5x)/5-3=(9x-3)/4
x-2/x+3-x+1/3-x=2x^2+6/x^2-9
2x+3/x+1 - 6/x =2
