Answer 1

Respuestas y procedimientos:

A) x + 7 = 22

x = 7 - 22

x = 15

B) x + 15 = 51

x = 15 + 51

x = 66

C) x - 19 = 40

x = 19 + 40

x = 59

D) x - 25 = 50

x = 25 + 50

x = 75

E) 6x = 42

x = 6x ÷ 6 = 42 ÷ 6

x = 42 ÷ 6

x = 7

F) 8x = 88

x = 8x ÷ 8 = 88 ÷ 8

x = 88 ÷ 8

x = 11

G) x / 3 = 9

x = 3 × x / 3 = 3 × 9

x = 3 × 9

x = 27

H) x / 8 = 7

x = 8 × x / 8 = 8 × 7

x = 8 × 7

x = 56

I) 5x - 5 = 2x + 16

x = 5x - 5 - 2x + 16

x = 5x - 2x = 16 + 5

3x = 16 + 5

3x = 21

x = 21 ÷ 3

x = 7

J) 5x + 10 = 2x + 40

x = 5x + 10 - 2x = 40

x = 5x - 2x = 40 - 10

3x = 40 - 10

3x = 30

30 ÷ 3

x = 10

K) 4x - 3 = 3x + 2

x = 4x - 3 - 3x = 2

x = 4x - 3x = 2 + 3

x = 2 + 3

x = 5

L) 6x - 6 = 5x + 5

x = 6x - 6 - 5x = 5

x= 6x - 6 - 5x = 5

x = 6x - 5x = 5 + 6

x = 5 + 6

x = 11
