Answer 1

Respuesta:

ejercicio 1 :

3x + 10 = 60 + x

3x - x = 60 - 10

2x = 50

x = 50/2

x = 25

ejercicio 2:

7x + 49 = 2x + 94

7x- 2x = 94 - 49

5x = 45

x= 45/5

x = 9

ejercicio 3 :

9x + 156 = 7x + 184

9x - 7x = 184 - 156

2x = 28

x = 28/2

x = 14

ejercicio 4 :

6x + 175 = 3x + 127

6x - 3x = 127 - 175

3x = -48

x = -48/3

x = -16
