Question

3x\5 -2+ 3x/2 -x/10= 0

Answer 1

$\frac{3x}{5} - 2 + \frac{3x}{2} - \frac{x}{10} = 0$

sacamos mcm(5,2,10)=10

$\frac{6x - 20 + 15x - x}{10} = 0 \\ \frac{20x - 20}{10} = 0$
pasamos a multiplicar el 10

$20x - 20 = 0 \times 10 \\ 20x - 20 = 0 \\ \\ pasa \: a \: sumar \: el \: - 20 \\ \\ 20x = 20 \\pasa \: dividir \: el \: 20 \\ \\ x = 20 \div 20 \\ \boxed{x = 1}$
