Answer 1

Vamos lá :

a)

g - 5 = 7

g =  7 + 5 =  12

b)

2r + 3 = 15

2r =  15 - 3

2r =  12

r =  12/2 =  6

C)

x + 9 = 11

x =  11 - 9 =  2

d)

x + 7= 25

x =  25 - 7 =  18

e)

3m + 1 = 10

3m =  10 - 1

3m =  9

m =  9/3 =  3

f)

7h = 0

h =  0/7 =  0

g)

2r = 1 /2

r =  1/2 / 2

r =  1/2 * 1/2

r =  1/4

Espero ter ajudado !!!

 

Answer 2

Oie, Td Bom?!

a)

g - 5 = 7

g = 7 + 5

g = 12

b)

2r + 3 = 15

2r = 15 - 3

2r = 12

r = 12/2

r = 6

c)

x + 9 = 11

x = 11 - 9

x = 2

d)

x + 7 = 25

x = 25 - 7

x = 18

e)

3m + 1 = 10

3m = 10 - 1

3m = 9

m = 9/3

m = 3

f)

7h = 0

h = 0/7

h = 0

g)

2r = 1/2

r = 1/2 ÷ 2

r = 1/2 . 1/2

r = 1/4
