Answer 1

Explicación paso a paso:

1) 6x + 10 = 3x + 20 + x

2x = 10

x= 5

2)  5x - 10 + x = 4x + 20

6x - 10 = 4x + 20

2x= 30

x= 15

3) 2x + 6 + 3x = 4x + 10

5x + 6= 4x + 10

x= 4

4)  18x - 10 + 2x = 12x + 70

20x - 10 = 12x + 70

8x= 80

x= 10

5) 5x - 10 + 2x = 15 - x + 7

7x - 10= 22 - x

8x = 32

x= 4

6) 19x - 10 + 3x = 7x + 20

22x - 10 = 7x + 20

15x= 30

x= 2

7) 3 (x - 9) = 81

3x - 27= 81

3x= 108

x= 36

Answer 2

a) 6x + 10 = 3x + 20 + x

6x - 4x = 20 - 10

2x = 10

x = 5

b) 5x - 10 + x = 4x + 20

2x = 30

x = 15

c) 2x + 6 + 3x = 4x + 10

x = 4

d) 18x - 10 + 2x = 12x + 70

20x - 12x = 70 + 10

8x = 80

x = 10
