Answer 1

Respuesta:

1)

$\frac{x - 2}{3} = \frac{1x + 3}{4} \\ 4x - 8 = 3x + 9 \\ 4x - 3x = 9 + 8 \\ x = 17$

2)

$\frac{x - 4}{6} = \frac{x + 2}{7} \\ 7x - 28 = 6x + 12 \\ 7x - 6x = 12 + 28 \\ x = 40$

3)

$\frac{2x}{4} - \frac{1}{2} = 5 \\ 2x - 2 = 20\\ 2x = 20 + 2 \\ 2x = 22 \\ x = \frac{22}{2} \\ x = 11$

4)

$\frac{5x - 3}{3} - 2 = 6 \\ 5x - 3 -6 = 18 \\ 5x - 9 = 18 \\ 5x = 18 + 9 \\ 5x = 27 \\ x = \frac{27}{5}$

5)

$\frac{x}{2} + \frac{x}{9} - 1 = 21 \\ 9x + 2x - 18 = 378 \\ 11x = 378 + 18 \\ 11x = 396 \\ x = \frac{396}{11} \\ x = 36$
