Answer 1

Resposta:

a)-18

b)5

c)-32

d)52

e)-38

f)6

g)8

h)5

Explicação passo-a-passo:

a) -x-5=13

-x=13+5

-x=18

x= -18

b)20-x=15

-x= 15 - 20

-x= -5

x=5

c) 2-x=34

-x = 34 -2

-x= 32

x= -32

d)-x+10=-42

-x = -42 -10

-x= -52

x=52

e) -x-8=30

-x=30+8

-x=38

x=-38

f)-6-x=-12

-x=-12+6

-x=-6

x=6

g)-5x=-40

x=-40/-5

x=8

h)-10x=-50

x=-50/-10

x=5
