2m - 15 = 21

2m = 21 + 15

2m = 36

m = 36/2

m = 18

b)

y - 9 = 12

y = 12 + 9

y = 21

c)

6x + 18 = 24

6x = 24 - 18

6x = 6

x = 6/6

x = 1

d)

t + 15 = 25

t = 25 - 15

t = 10

e)

6f = 36

f = 36/6

f = 6

f)

9 + c = 18

c = 18 - 9

c = 9

g)

7b - 11 = 10

7b = 10 + 11

7b = 21

b = 21/7

b = 3

h)

8/2 = 4

i)

f/9 = 7

f = 27

espero que te ayude <3
