Question

alguien me ayuda?esque no entiendo como hacerlo

Answer 1

Respuesta:

PRIMERA PARTE

B) a -3 = 12

a = 12 +3

a = 15

C) y +8 = 16

y = 16 - 8

y = 8

D) b - 10 = 5

b = 5+10

b = 15

E) m -7 = 13

m = 13 +7

m = 20

F) h + 6 = 18

h = 18-6

h = 12

G) k -2 = 23

k = 23+2

k = 25

H) f +9 = 24

f = 24-9

f = 15

SEGUNDA PARTE

B) 5h = 35

h = 35÷5

h = 7

C) 4m = 32

m = 32÷4

m = 8

D) 9a = 36

a = 36÷9

a = 4

E) 2b = 40

b = 40÷2

b= 20

F) 6y =30

y = 30÷6

y = 5

G) 7x = 21

x = 21÷7

x = 3

H) 8k = 8

k = 8÷8

k = 1

TERCERA PARTE

B) 7x -11 = 10

7x = 10 + 11

7x = 21

x = 21 ÷ 7

x= 3

C) 3b +4 = 19

3b = 19 -4

3b = 15

b= 15 ÷ 3

b = 5

D) 9y -15= 21

9y = 21 +15

9y = 36

y = 36 ÷9

y = 4

E) 2d +14 = 30

2d = 30 -14

2d = 16

d = 16 ÷2

d = 8

F) 5h -12= 18

5h = 18 +12

5h = 30

h = 30 ÷5

h = 6

G) 6k -17 = 37

6k = 37 +17

6k = 54

k = 54 ÷ 6

k = 9

H) 4h +18 = 46

4h = 46 -18

4h = 28

h = 28 ÷ 4

h= 7
