Ayudenme con esto ejercicios plis . Porfavor la nececito porfaaaaaa

Answer 1

Solución:

a.

23 + x = 52

x = 52 – 23

x = 29

23 + 29 = 52

52 = 52

b.

3 × n = 51

n = 51 ÷ 3

n = 17

3 × 17 = 5

51 = 51

c.

8 + y – 12 = 1

y = 1 + 12 – 8

y = 5

8 + 5 – 12 = 1

13 – 12 = 1

1 = 1

d.

5 × p = 30

p = 30 ÷ 5

p = 6

5 × 6 = 30

30 = 30

e.

50 = t – 1

50 + 1 = t

51 = t

t = 51

50 = 51 – 1

50 = 50

f.

64 ÷ 8 + u = 30

8 + u = 30

u = 30 – 8

u = 22

64 ÷ 8 + 22 = 30

8 + 22 = 30

30 = 30

g.

r = 24 – 12 ÷ 4

r = 24 – 3

r = 21

h.

56 ÷ 8 – 7 = j

7 – 7 = j

0 = j

j = 0

i.

543 + 762 + h = 2653

1305 + h = 2653

h = 2653 – 1305

h = 1348

543 + 762 + 1348 = 2653

2653 = 2653

j.

144 ÷ s = 12

s = 144 ÷ 12

s = 12

144 ÷ 12 = 12

12 = 12
