Answer 1

Resposta:

a) x=42-28

x=14

b) x=-28+15

x=-13

c) x= -37-63

x=-100

d)z= 5

e)x+15=0

x=-5

f)-x=-28

x=28

g) x+6=2

x=-4

h)-x=44

x=-44

Answer 2

a) 42-28=x

14 = x -> x= 14

b) x-15=-28

x= - 28 + 15

x= - 13

c) x+63=-37

x= - 37 - 63

x= - 100

d) z+3=12-4

z= 12 - 4 - 3

z= 8 - 3

z= 5

e) x+4+5+6=0

x + 9 + 6 = 0

x + 15 = 0

x= 0 - 15

x= - 15

f) 3-x=-25

- x = - 25 - 3

- x= - 28 ( - 1)

x= 28

g) 2x-x+6=2

x = 2 - 6

x= - 4

h) -5x+4x-14=-30

- x = - 30 + 14

- x= - 16 ( - 1)

x= 16
