Solución a los problemas :

6)

$\frac{2x - 1}{x + 4} = \frac{6x - 3}{3x + 2}$

$(2x - 1)(3x + 2) = (6x - 3)(x + 4)$

$6 {x}^{2} + 4x - 3x - 2 = 6 {x}^{2} + 24x - 3x - 12$

$6 {x}^{2} + x - 2 = 6 {x}^{2} + 21x - 12$

$6 {x}^{2} - 6 {x}^{2} - 2 + 12 = 21x - x$

$10 = 20x$

$\frac{10}{20} = x$

$\frac{1}{2} = x$

Literal C ✓

7)

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

$2x - 1 = - 3(x + 4)$

$2x - 1 = - 3x - 12$

$2x + 3x = - 12 + 1$

$5x = - 11$

$x = - \frac{11}{5}$

Literal B ✓

8)

$9x = 2(3x - 4)$

$9x = 6x - 8$

$9x - 6x = - 8$

$3x = - 8$

$x = - \frac{8}{3}$

Literal D ✓

9)

$7(3x - 5) = 24$

$21x - 35 = 24$

$21x = 24 + 35$

$21x = 59$

$x = \frac{59}{21}$

Literal B ✓

10)

$(3.3)(2x) = 8.25$

$6.6x = 8.25$

$x = \frac{8.25}{6.6}$

$x = 1.25$

Literal A ✓
