Question

Qual é a resposta das seguintes equações: (x-8 = -10) (x+9 = -1) (3x = 12) (9x = 18) (35x = -105) (7x-1 =13)

Answer 1

x - 8 = -10
x = -10 + 8
x = -2

x + 9 = -1
x = =1 - 9
x = -10

3x = 12
x = 12/3
x = 4

9x = 18
x = 18/9
x = 2

35x = -105
x = -105/35
x = -3

7x - 1 = 13
7x = 13 + 1
7x = 14
x = 14/7
x = 2

Answer 2

Boa noite Larissa

a)

x - 8 = -10
x = -10 + 8
x = -2

b)

x + 9 = -1
x = -1 - 9 = -10

c)

3x = 12
x = 12/3 = 4

d)

9x = 18
x = 18/9 = 2

e)

35x = -105
x = -105/35 = -3

f)

7x - 1 = 13
7x = 13 + 1 = 14
x = 14/7 = 2
