Answer 1

Respuesta:

allí está la respuesta

a. 2x + 5 = 19

2x = 19 - 5

2x = 14

x = 7

b. 5x – 3 = 3x + 7

5x - 3x = 7 + 3

2x = 10

x = 5

c. 9 + 7x - 3 - 4x = 27

3x + 6 =27

3x = 27 - 6

3x = 21

x = 7

d. 3x - 4 = 20

3x = 20+4

3x = 24

x = 8

e. 4x + 9 + x = 24

5x = 24 - 9

5x = 15

x = 3

f. 8x – 7 + x = 5x + 21

9x - 5x = 21 +7

4x =28

x = 7

g. 9x + 17 – 6 = 4x + 26

9x - 4x = 26 -17+6

5x = 15

x = 3

h. 11x + 14 - 7x – 5 = 39 - X

4x + x = 39 -14 +5

5x = 30

x = 6

i. 4x + 1 + 10 + 2x = x + 71

6x + 11= x+71

6x - x = 71 -11

5x = 60

x = 12

j. 3x - 2 + 6x = 15 + 2x + 11

9x -2x = 15+11+2

7x = 28

x = 4

k. 5x + 15 - 11 = 2x + 19

5x -2x = 19 -15+11

3x = 15

x = 5

1. 21 + 6x - 6 - 2x = 60 – X

4x +15 = 60 - x

4x + x = 60 - 15

5x = 45

x = 9
