3: 30 x = 60
4: -2 x = -14 x
5: 2x + 2 = 12
6: 9x - 4 = 14
7: 9x - 2 = 4 - 2
8: 16x + 3 - 4 - 2 = - 4 - 2
9 : 12x - 2 - 4 = - 3 - 4 - 4​

Answer 1

Respuesta:

X+2=4

X= 4-2

X= 2

X-4=12

X= 12+4

X= 16

30X= 60

X= 60:30

X= 2

2X+2=12

2X= 12-2

2X= 10

X= 10:2

X= 4

9X-4=14

9X= 14+4

9X= 18

X= 18:9

X= 2
