Answer 1

Explicación paso a paso:

1) x = 5 - 4 - 1

x = 0

2) x = 0

3 ) 3- 7- 24 = x

-28 = x ou - x = 28

4) 40 - 1 - 2 - 3 = - v

34 = - v o v = - 34

5) 4 - x - 8 = 30 -6

- x = 30- 6 - 4

- x = 20 o x = 6

6) - x = 30 + 8 - 4 + 2

- x = 32 o x = - 32

7) 2 + x - 1 = 7 + 7

1 + x = 14

x = 14 - 1

x = 13
