Answer 1

Resposta:

a) x+5=8

x=8-5

x=3

b)x-4=3

x=3+4

x=7

c)x+6=5

x=6-5

x=1

d)x-7=-7

x=-7+7

x=0

e)x+9=-1

x=-1-9

x=-10

f)x+28=11

x=11-28

x=-17

g)x-109=5

x=5+109

x=114

h)x-39=-79

x=-79+39

x=-40

i) 10=x+8

10-8=x

x=2

j)15=x+20

15-20=x

x=-5

k)4=x-10

4+10=x

x=14

l)7=x+8

7-8=x

x=-1

m)0=x+12

0-12=x

x=-12

n)-3=x+10

-3-10=x

x=-13
