Giải:
Ta có: \(\frac{1}{2}\left(x+1\right)\) + \(\frac{1}{4}\left(x+3\right)\) = \(3-\frac{1}{3\left(x-2\right)}\)
⇔ \(\frac{1}{2}x\) + \(\frac{1}{2}\) + \(\frac{1}{4}x\) + \(\frac{3}{4}\) = 3 - \(\frac{1}{3\left(x-2\right)}\)
⇔ \(\frac{3}{4}x\) + \(\frac{5}{4}\) - 3 + \(\frac{1}{3\left(x-2\right)}\) = 0
⇔
Còn lại bạn tự làm nhá!

Giải các phương trình
1,\(3x-1=0\\\) 4, \(\dfrac{x}{3}-\dfrac{x}{5}=4\)
2, \(2-x=3x+1\) 5, \(\dfrac{x-1}{4}+\dfrac{2x+1}{6}=\dfrac{3}{2}\)
3, \(2\left(x-2\right)-1=5x\)
Giải phương trình:
a) (x + 5)(x + 2) = 3(4x - 3) + (x - 5)2
b) 12 - 2(1 - x)2 = 4(x - 2) - (x - 3)(2x - 5)
c) (x - 3)3 - 2(x - 1) = x(x - 2)2 - 5x2
d) x(x + 3)2 - 3x = (x + 2)3 + 1
