Answer 2

¡Hola!

Problema A.

$9x + 10 = 28 \\ \\ \\ 9x = 28 - 10 \\ \\ \\ 9x = 18 \\ \\ \\ x = \frac{18}{9} \\ \\ \\ \boxed{x = 2}$

Problema B.

$2x +8 = 32 \\ \\ \\ 2x = 32 - 8 \\ \\ \\ 2x = 24 \\ \\ \\ x = \frac{24}{2} \\ \\ \\ \boxed{x = 14}$

Problema C.

$2x - 34 = - 20 \\ \\ \\ 2x = - 20 + 34 \\ \\ \\ 2x = 14 \\ \\ \\ x = \frac{14}{2} \\ \\ \\ \boxed{x = 7}$

Problema D.

$5x - 4 = 16 \\ \\ \\ 5x = 16 + 4 \\ \\ \\ 5x = 20 \\ \\ \\ x = \frac{20}{5} \\ \\ \\ \boxed{x = 4}$

Problema E.

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

Espero que sirva y saludos.
