Question

me ayudan porfa es urgente lo nesesito ahora ​

Answer 1

12x + 5 = 20

12x = 15

x = 15/12

x = 5/4

15x + 1 = 16

15x = 15

x = 15/15

x = 1

5x + 5x + 8x = 30

18x = 30

x = 30/18

x = 5/3

9x = 18

x = 18/9

x = 2

x - 27 = 40

x = 40 + 27

x = 67

3x + 5 = 50

3x = 45

x = 45/3

x = 15

4x + 5x + 8x = 30

17x = 30

x = 30/17

4x + 2 = 60

4x = 60 - 2

4x = 58

x = 58/4

x = 29/2
