​ Porfavor es urgente es para hoy

Answer 1

Respuesta:

X = 2

X = 4

X = 20

X = 8

X = 3

X = 18

Explicación paso a paso :

2x + 5 = 9

2x = 9 - 5

2x = 4

X = 4 ÷ 2

X = 2

8x - 10 = 22

8x = 22 + 10

8x = 32

X = 32 ÷ 8

X = 4

X + 20 = 40

X = 40 - 20

X = 20

X + X = 15 + 1

2X = 16

X = 16 ÷ 2

X = 8

20X + 6 = 2X + 60

20X - 2X = 60 - 6

18X = 54

X = 54 ÷ 18

X = 3

X ÷ 3 = 6

X = 6 (3)

X = 18
