Answer 1

h) x + 13 = 23

x = 23 - 13

x = 10

i) 18x - 43 = 65

18x = 65 + 43

x = 108/18

x = 6

j) 23x - 16 = 14 - 7x

23x + 7x = 14 + 16

30x = 20

x = 20/30  (simplificamos por 10)

x = 2/3

k) 18x + 36 = 16x + 80

18x - 16x = 80 - 36

2x = 44

x = 44/2

x = 22

l) 2x + x = 39

3x = 39

x = 39/3

x = 13

m) 3x - 27 = 36

3x = 36 + 27

x = 63/3

x = 21

n) x + x + 7 = 37

2x = 37 - 7

x = 30/2

x = 15

o) 5x - 10 = 3x + 25

5x - 3x = 25 + 10

2x = 35

x = 35/2

p) 2x + 8 = - 2x + 24

2x + 2x = 24 - 8

4x = 16

x = 16/4

x = 4
