Question

resuelve las siguientes ecuaciones con Q​

Answer 1

Explicación paso a paso:

• ....
• $\frac{2x}{3} + \frac{x}{4} = \frac{1}{2} \\ \frac{8x}{12} + \frac{3x}{12} = \frac{1}{2} \\ \frac{11x}{12} = \frac{1}{2} \\ 22x = 12 \\ x = \frac{6}{11}$
• ....
• $\frac{3x}{6} + \frac{4}{2} = \frac{x}{4} \\ \frac{x}{2} + \frac{4}{2} = \frac{x}{4} \\ \frac{2x}{4} - \frac{x}{4} = - 2 \\ \frac{x}{4} = - 2 \\ x = - 8$
• .....
• $\frac{2x}{8} + \frac{x}{2} = \frac{5}{3} \\ \frac{x}{4} + \frac{2x}{4} = \frac{5}{3} \\ \frac{3x}{4} = \frac{5}{3} \\ 9x = 20 \\ x = \frac{20}{9}$
