Answer 1

Respuesta:

1- x - 1÷2 - 2 = 5

x - 1 ÷2 = 7

x - 1 ÷ 2 = 7÷1

x - 1 = 14

x = 14 +1

x= 15

2- x- 1 ÷3 + x ÷4 = 2

4x - 4 + 3x ÷12 = 2 ÷ 1

4x - 4 + 3x = 24

4x + 3x = 24 + 4

7x = 28

x = 4

3- 2x + 3 = 7x - 7

3 + 7 = 7x - 2x

10 = 5x

x= 2

4- x+ 1÷ 5 = 3x - 9 ÷ 3

3x + 3 = 15x - 3x

3 + 45 = 15x - 3x

48 = 12x

4 =x

5 - x÷2 -3x ÷ 5 = x - 6 ÷ 2

5x - 6x ÷ 10 = x - 6÷ 2

-1 ÷10 = x - 6 ÷2

- 2x = 10x - 60

60 = 10x + 2x

60 = 12x

5 =x
