Question

con procedimiento : a) x + 3 = 7 – 4 b) x + (-9) = - 8 c) 2 – x = - 27 + 4 d) x – 5- (-1) = 8 e) 2 = - x + 15 – 43 f) -x + 4 – 7 = -6 g) 9 – 8 = - x + 3 h) x - 61 = – ( -2

Answer 1

a) x + 3 = 7 – 4

x + 3 = 3

x = 3 - 3

x = 0

b) x + (-9) = - 8

x - 9 = - 8

x = - 8 + 9

x = 1

c) 2 – x = - 27 + 4

2 - x = - 23

- x = - 23 - 2

- x = - 25

x = 25

d) x – 5- (-1) = 8

x - 5 + 1 = 8

x - 5 = 8 - 1

x - 5 = 7

x = 7 + 5

x = 12

e) 2 = - x + 15 – 43

2 = - x - 28

2 + x = - 28

x = - 28 - 2

x = - 30

f) -x + 4 – 7 = -6

- x - 3 = - 6

- x = - 6 + 3

- x = - 3

x = 3

g) 9 – 8 = - x + 3

1 = - x + 3

1 + x = 3

x = 3 - 1

x = 2

h) x - 61 = – ( -2)

x - 61 = 2

x = 2 + 61

x = 63

Espero haber ayudado.
