Question

me pueden explicar el paso a paso de la siguiente ecuación?6/10 • X - 3 +12/10 = 5/10 + X​

Answer 1

Respuesta:

$\frac{6}{10} x - 3 + \frac{12}{10} = \frac{5}{10} + x \\ \\ \frac{3}{5} x - 3 + \frac{6}{5} = \frac{1}{2} + x \\ \\ \frac{3}{5} x - x = \frac{1}{2} + 3 - \frac{6}{5} \\ \\ \frac{3 - 5}{5} x = \frac{5 + 30 - 12}{10} \\ \\ - \frac{2}{5} x = \frac{23}{10} \\ \\ x = \frac{23}{10} \div ( - \frac{2}{5} ) \\ \\ x = - \frac{115}{20} \\ \\ x = - \frac{23}{4} \\ \\ comprobacion \\ \frac{6}{10} \times ( - \frac{23}{4} ) - 3 + \frac{12}{10} = \frac{5}{10} + ( - \frac{23}{4} ) \\ \\ - \frac{138}{40} - 3 + \frac{6}{5} = \frac{1}{2} - \frac{23}{4} \\ \\ \frac{ - 138 - 120 + 48}{40} = \frac{2 - 23}{4} \\ \\ - \frac{210}{40} = - \frac{21}{4} \\ \\ - \frac{21}{4} = - \frac{21}{4}$
