NESECITO AYUDA ES PARA HOY!​

Answer 1

Respuesta:

1. 7x + 30 = 324

7x = 324 - 30

7x = 294

x = 294/7

x= 42

comprobacion:

7 (42) + 30 = 324

324 = 324

2. r/6 + 4 = 58

r/6 = 58 - 4

r/6 = 54

r = 54 × 6

r = 324

comprobacion:

(324) / 6 + 4 = 58

(54) + 4 =58

58 = 58

3. b/12 - 5 = 1

b/12 = 1 + 5

b/12 = 6

b = 6 × 12

b = 72

comprobacion:

( 72 ) / 12 - 5 = 1

( 6) - 5 = 1

1 = 1

4. 13x - 23 = 81

13x = 81 + 23

13x = 104

x = 104 / 13

x = 8

comprobacion

13 (8) - 23 = 81

104 - 23 = 81

81 = 81

Espero haberte ayudado :)
