Holu :^

Explicación paso a paso:

a) y = 8

3y + 1 = 25

3y = 25 - 1

3y = 24

y = 24/3

y = 8

Comprobación:

8(3) + 1 = 25

24 + 1 = 25

25 = 25

b) x = 7

2x + 2 = 16

2x = 16 - 2

2x = 14

x = 14/2

x = 7

Comprobación:

7(2) + 2 = 16

14 + 2 = 16

16 = 16

c) c = 5

2c + 9 = 19

2c = 19 - 9

2c = 10

c = 10/2

c = 5

Comprobación:

5(2) + 9 = 19

10 + 9 = 19

19 = 19

d) x = 4

3x + 3 = 15

3x = 15 - 3

3x = 12

x = 12/3

x = 4

Comprobación:

3(4) + 3 = 15

12 + 3 = 15

15 = 15

e) m = 10

2m - 7 = 13

2m = 13 + 7

2m = 20

m = 20/2

m = 10

Comprobación:

10(2) - 7 = 13

20 - 7 = 13

13 = 13

f) y = 1

3y - 1.5 = 1.5

3y = 1.5 + 1.5

3y = 3

y = 3/3

y = 1

Comprobación:

1(3) - 1.5 = 1.5

3 - 1.5 = 1.5

1.5 = 1.5

g) a = 7

7a +21 = 70

7a = 70 - 21

7a = 49

a = 49/7

a = 7

Comprobación:

7(7) + 21 = 70

49 + 21 = 70

70 = 70
