a) / 3x+ 2/ = 3
<=> 3x+2 = 9
<=> x= $\frac{7}{3}$
b)
/1-x/= /3x+2/
<=> 1-x = 3x+2
<=> -4x = 1
<=> x = $\frac{-1}{4}$
c) /4x-3/= 2x-1
<=> 4x-3 = $4x^{2}$ - 4x+1
<=> $-4x^{2}$ + 8x -4 =0
<=> x=1
d) √x-3 = x-9
<=> x-3 = $x^{2}$ -18x + 81
<=> $-x^{2}$ +19x - 84 =0
<=> \(\left[ \begin{array}{l}x=12\\x=7\end{array} \right.\)
e) √2x+3 = √4-3x
<=> 2x+3 = 4-3x
<=> 5x=1
<=> x=$\frac{1}{5}$
