Answer 1

Respuesta:

a) 5x + 4 = 19

5x = 19 - 4

x = 15:5

x = 3

b) 8x + 7 = 71

8x = 71-7

x = 64:8

x = 8

c) 2x - 19 = 9

2x = 9 + 19

x = 28:2

x = 14

d) 6x + 11 = 4x + 25

6x-4x = 25-11

2x = 14

x = 14: 2

x = 7

e) 13x - 9 = 5x - 1

13x-5x = 9-1

8x = 8

x = 8:8

x = 1

Espero haberte ayudado
