Answer 1

Explicación paso a paso:

a) 5x + 6 = 21

5x = 21 - 6

5x = 15

x = 3

b) 2x + 8 = 18

2x = 18 - 8

2x = 10

x = 5

c) x + 2 = 9

x = 9 - 2

x = 7

d) 2x + 4 = 6

2x = 6 - 4

2x = 2

x = 1

e) 3x - 20 = 4

3x = 20 + 4

3x = 24

3x = 8

f) x + 4 = 10

x = 10 - 4

x = 6

g). x + 1 = 10

x = 9

h). x - 5 = 5

x = 10

i). 4x - 8 = 0

4x = 8

x = 2

j). 7x - 28 = 0

7x = 28

x = 4
