resolva.as equações pfv me ajudem obg!​

Answer 1

a) x=11-15

x=-4

b) 4x=18-2

4x=16

x=16:4

x=4

c) x=18:9

x=2

d) 6x-2x=16

4x=16

x=16:4

x=4

e) 3x-4x=9+2

-x=11

x=-11

Answer 2

Resposta:

a) x + 15 = 11

x = 11 - 15

x = -4

b)4x + 2 = 18

4x = 18 - 2

4x = 16

x = 16 / 4

x = 4

c)9x = 18

x = 18 / 9

x = 2

d)6x = 2x + 16

6x - 2x = 16

4x = 16

x = 16 / 4

x = 4

e)3x - 2 = 4x + 9

3x - 4x = 9 + 2

-x = 11 ×(-1)

x = -11
