Question

resolver ecuaciones
x+5=20 6x-3=21 2x+3=13 3x+4=22



x+9=18 2x+4=12 4x-2=10

Answer 1

X=20-5. 6x=21+3
X=15. 6x=24
X=24/6
X=4. 2x=13-3 2x=10 X=10/2 X=5

Answer 2

x + 5 = 20

x = 20 - 5

x = 15

Respuesta :

x = 5



6x - 3 = 21

6x = 21 + 3 

6x = 24

x = 24/6

x = 4

Respuesta : 

x = 4



2x + 3 = 13

2x = 13 - 3

2x = 10

x = 10/2

x = 5

Respuesta : 

x = 5



3x + 4 = 22

3x = 22 - 4

3x = 18

x = 18/3

x = 6

Respuesta : 

x = 6



x + 9 = 18

x = 18 - 9

x = 9

Respuesta : 

x = 9





2x + 4 = 12

2x = 12 - 4

2x = 8

x = 8/2

x = 4

Respuesta : 

x = 4



4x - 2 = 10

4x = 10 + 2 

4x = 12

x = 12/4

x = 3

Respuesta : 

x = 3
