Question

c 4x=24. d 5x-7=28. e 6x+2=50. f 7x-47=2 g x + 15 = 20 h x - 6 = 12 i x + 11 = 31 F 3 x = 5 ​

Answer 1

Resposta:

c) 4x = 24

x = 24/4

x = 6

d) 5x - 7 = 28

5x = 28 + 7

5x = 35

x = 35/5

x = 7

e) 6x + 2 = 50

6x = 50 - 2

6x = 48

x = 48/6

x = 8

f) 7x - 47 = 2

7x = 2 + 47

7x = 49

x = 49/7

x = 7

g) x + 15 = 20

x = 20 - 15

x = 5

h) x - 6 = 12

x = 12 + 6

x = 18

i) x + 11 = 31

x = 31 - 11

x = 20

f) 3x = 5

x = 5/3
