Question

Resuelva cada ecuación

X + 2/3=4\5
2/3 x + 1/2 =5/6

Answer 1

Resolvemos para x:

$x + \frac{2}{3} = \frac{4}{5} \\ x = \frac{4}{5} - \frac{2}{3} = \frac{12 - 10}{15} = \frac{2}{15} \\ x = \frac{2}{15}$

Resolvemos para x:

$\frac{2}{3} x + \frac{1}{2} = \frac{5}{6} \\ \frac{2}{3} x = \frac{5}{6} - \frac{1}{2} = \frac{5 - 3}{6} = \frac{2}{6} = \frac{1}{3} \\ x = \frac{1}{3} \div \frac{2}{3} = \frac{3}{6} = \frac{1}{2}$

Answer 2

Respuesta:

Estás son las respuestas.

Explicación paso a paso:

1. $x + \frac{2}{3} = \frac{4}{5} \\ x = \frac{4}{5} - \frac{2}{3} \\ x = \frac{12 - 10}{15} = \frac{ 2}{15} = \frac{ 2}{5}$
2. $\frac{2}{3} x + \frac{1}{2} = \frac{5}{6} \\ \frac{2}{3} x = \frac{5}{6} - \frac{1}{2 } \\ \frac{2}{3} x = \frac{10 - 6}{12} \\ \frac{2}{3} x = \frac{4}{12} \\ x = \frac{ \frac{4}{12} }{ \frac{2}{3} } \\ x = \frac{12}{24} \\ x = \frac{1}{2}$
