Resposta:

OLÁ

A)

$15x = 345 \\ x = \frac{345}{15} \\ \boxed{ \blue{x = 23}}$

B)

$x + 150 = 237 \\ x = 237 - 150 \\ \boxed{ \blue{x = 87}}$

C)

$y - 56 = 14 \\ y = 14 + 56 \\ \boxed{ \blue{y = 70}}$

D)

$5x = 25840 \\ x = \frac{25840}{5} \\ \boxed{ \blue{x = 5168}}$

E)

$2x + 5 = 9 \\ 2x = 9 - 5 \\ 2x = 4 \\ x = \frac{4}{2} \\ \boxed{ \blue{x = 2}}$

F)

$8x = 320 \\ x = \frac{320}{8} \\ \boxed{ \blue{x = 40}}$

G)

$x + 0 = 250 \\ x = 250 - 0 \\ \boxed{ \blue{x = 250}}$

H)

$y - 452 = 448 \\ y = 440 - 452 \\ \boxed{ \blue{y = - 12}}$

I)

$x + 80 = 13 \\ x = 13 - 80 \\ \boxed{ \blue{x = - 67}}$
