alguém me ajuda ​

Answer 1

Resposta:

$h)x-39=-79=>x=-79+39=>x=-40\\i)10=x+9=>x=10-9=>x=1\\j)15=x+20=>x=15-20=>x=-5\\k)4=x-10=>x=4+10=>x=14\\l)7=x+8=>x=7-8=>x=-1\\m)0=x+12=>x=-12\\n)-3=x+10=>x=-3-10=>x=-13$

Espero ter ajudado...

Answer 2

→ Cálculo :

h) x - 39 = -79

x = -79 + 39

x = -40

i) 10 = x + 9

-x = 9 - 10

- x = -1

x = 1

j) 15 = x + 20

-x = 20 - 15

-x = 5

x = -5

k) 4 = x - 10

-x = -10 - 4

-x = -14

x = 14

1) 7 = x + 8

-x = 8 - 7

-x = 1

x = -1

m) 0 = x + 12

0 - x = 12

-x = 12

x = -12

n) -3 = x + 10

-x = 10 + 3

-x = 13

x = -13
