$\frac{3}{2}$.(x - $\frac{5}{4}$) - $\frac{5}{8}$ = x
<=> $\frac{3}{2}$.x - $\frac{15}{8}$ - $\frac{5}{8}$ = x
<=> $\frac{3}{2}$.x - $\frac{15}{8}$ - $\frac{5}{8}$ - x = 0
<=> $\frac{1}{2}$.x = $\frac{15}{8}$ + $\frac{5}{8}$
<=> $\frac{1}{2}$.x = $\frac{5}{2}$
<=> x = $\frac{5}{2}$ : $\frac{1}{2}$
<=> x = 5
Vậy x = 5
5x - $\frac{2}{3}$ = 5 - $\frac{3x}{2}$
<=> $\frac{30x}{6}$ - $\frac{4}{6}$ = $\frac{30}{6}$ - $\frac{9x}{6}$
<=> 30x - 4 = 30 - 9x
<=> 30x + 9x = 30 + 4
<=> 39x = 34
<=> x = $\frac{34}{39}$
Vậy x = $\frac{34}{39}$
10x + $\frac{3}{12}$ = 1 + 6 + $\frac{8x}{9}$
<=> 10x + $\frac{1}{4}$ = 7 + $\frac{8x}{9}$
<=> $\frac{360x}{36}$ + $\frac{9}{36}$ = $\frac{252}{36}$ + $\frac{32x}{36}$
<=> 360x + 9 = 252 + 32x
<=> 360x - 32x = 252 - 9
<=> 328x = 243
<=> x = $\frac{243}{328}$
Vậy x = $\frac{243}{328}$
7x - $\frac{1}{6}$ + 2x = 16 - $\frac{x}{5}$
<=> $\frac{240x}{30}$ - $\frac{5}{30}$ + $\frac{60x}{30}$ = $\frac{480}{30}$ - $\frac{6x}{30}$
<=> 240x - 5 + 60x = 480 - 6x
<=> 300x + 6x = 480 + 5
<=> 306x = 485
<=> x = $\frac{485}{306}$
Vậy x = $\frac{485}{306}$
4(0,5 - 1,5x) = -5x - $\frac{6}{3}$
<=> 2 - 6x = -5x - $\frac{6}{3}$
<=> 5x - 6x = - $\frac{6}{3}$ - 2
<=> -x = -4
<=> x = 4
Vậy x = 4
