Answer 1

Explicación paso a paso:

a)

x + 7 = 22

x + 7 - 7 = 22 - 7

x = 15

b)

x + 15 = 51

x + 15 - 15 = 51 - 15

x = 36

c)

x - 19 = 40

x - 19 + 19 = 40 + 19

x = 59

d)

x - 25 = 50

x - 25 + 25 = 50 + 25

x = 75

e)

6x = 42

6x/6 = 42/6

x = 7

f)

8x = 88

8x/8 = 88/8

x = 11

g)

x/3 = 9

3(x/3) = 3(9)

x = 27

h)

x/8 = 7

8(x/8) = 8(7)

x = 56

I)

5x - 5 = 2x + 16

5x - 5 + 5 = 2x + 16 + 5

5x = 2x + 21

5x - 2x = 2x - 2x + 21

3x = 21

3x/3 = 21/3

x = 7

j)

5x + 10 = 2x + 40

5x + 10 - 10 = 2x + 40 - 10

5x = 2x + 30

5x - 2x = 2x - 2x + 30

3x = 30

3x/3 = 30/3

x = 10

k)

4x - 3 = 3x + 2

4x - 3 + 3 = 3x + 2 + 3

4x = 3x + 5

4x - 3x = 3x - 3x + 5

x = 5

l)

6x - 6 = 5x + 5

6x - 6 + 6 = 5x + 5 + 6

6x = 5x + 11

6x - 5x = 5x - 5x + 11

x = 11
