Question

resuelve las siguientes ecuaciones, PORFAVOR

Answer 1

1)

$13x - 14 = 2 - (7x + 9) + 6x \\ 7x - 16 = - 7x - 9 \\ 14x = 7 \\ x = \frac{1}{2}$

2)

$\frac{2(x + 2)}{6} + 3 = 2 - \frac{x - 2}{4 } \\ \frac{x + 2}{3} + 1 = - \frac{x - 2}{ 4} \\ 4x + 8 + 12 = - 3x + 6 \\ 7x = - 14 \\ x = - 2$

3)

$\frac{5x}{3} - x = \frac{5}{6} - 1 \\ 10x - 6x = 5 - 6 \\ 4x = - 1 \\ x = - \frac{1}{4}$

4)

$2x - 4(1 - 2x) = 8 - (4x - 3) - x \\ 2x - 4 + 8 = 8 - 4x + 3 - x \\ 7x = 7 \\ x = 1$

5)

$\frac{x}{2} - \frac{2(x + 2)}{7} = \frac{x - 3}{4} \\ 14x - 8(x + 2) = 7x - 21 \\ 7x - 8x - 16 = - 21 \\ - x = - 5 \\ x = 5$
