Explicación paso a paso:

suelve las ecuaciones(ejercicios del 1 al 10)

* 4(x – 5) = 21

4x-20=21

4x=21+20

x= 41/4

x= 10.25

*4(x–3) = 20

4x-12=20

4x=20+12

x=22/4

x=5.5

*3(x + 2) = 10

3x+6=10

3x= 10-6

x=4/3

x=1.3

*6(x – 7) = 24

6x-42=24

6x= 24+42

x= 66/6

x=11

*2(x + 3) = –10

2x+6= -10

2x= -10-6

x= -16/2

x= -8

*9(x + 1) = 27

9x+9=27

9x= 27-9

x= 18/9

x= 2

*3(x + 5) = –9

3x+15= -9

3x = -9-15

x= 24/3

x= 8

*3(x + 10) = 36

3x+30=36

3x= 36-30

x=6/3

x= 2

* 5(x –1) = –15

5x-5= -15

5x= -15+5

x= -10/5

x= -2

* 5(x – 6) = 13

5x-30= 13

5x= 13+30

x= 43/5

x= 8.6
