Question

A1 Resaha
a/ 3x + 5 - 0
B) 4x-28-0
el 5x +3x +40=0
a 2D +7D-49=0
el 6V -2v=36
f 10c-4c +30=0
g) 4V +5V-108​

Answer 1

Resposta:

A) 3x + 5 = 0

3x = -5

x = -5/3

B) 4x - 28 = 0

4x = 28

x = 28/4

x = 7

C) 5x + 3x + 40 = 0

8x = -40

x = -40/8

x = -5

D) 2D + 7D - 49 = 0

9D = 49

D = 49/9

E) 6v - 2v = 36

4v = 36

v = 36/4

v = 9

F) 10c - 4c + 30 = 0

6c = -30

c = -30/6

c = -5

G) 4v + 5v - 108 = 0

9v = 108

v = 108/9

v = 12
