Bài 1:
a: \(\Leftrightarrow29\left(x-5\right)=3\left(4x-3\right)\)
=>29x-145=12x-9
=>17x=134
=>x=134/17
b: =>2(5-3x)=2x-1
=>10-6x=2x-1
=>-8x=-11
=>x=11/8
c: =>4x-5=2x-2+x
=>4x-5=3x-2
=>x=3
d: =>7(x-5)=3(x+2)
=>7x-35=3x+6
=>4x=41
=>x=41/4
e: =>(2x+5)(x+5)-2x^2=0
=>2x^2+10x+5x+25-2x^2=0
=>15x+25=0
=>x=-5/3

a: Thay x=16 vào B, ta được:
\(B=\dfrac{4-2}{4-3}=\dfrac{2}{1}=2\)
b: Ta có: \(A=\dfrac{x}{x-4}+\dfrac{1}{\sqrt{x}-2}+\dfrac{1}{\sqrt{x}+2}\)
\(=\dfrac{x+\sqrt{x}-2+\sqrt{x}+2}{\left(\sqrt{x}-2\right)\left(\sqrt{x}+2\right)}\)
\(=\dfrac{\sqrt{x}}{\sqrt{x}-2}\)
