Answer 1

Resposta:

a) 15/2

b) 8/5

c) 5

d) 5

e) 9

Explicação passo-a-passo:

a)

5x+12=3x+27

5x - 3x = 27 - 12

2x = 15

x = 15/2

b)

5x+4=12

5x = 12 - 4

5x = 8

x = 8/5

c)

8x=40

x = 40/8

x = 5

d)

x+4=9

x = 9 - 4

x = 5

e)

2*(x+4)=26

2x + 8 = 26

2x = 26 - 8

2x = 18

x = 18/2

x = 9

Answer 2

Resposta:

a)5x+12=3x+27

5x-3x=27-12

2x=15

x=15/2

b)5x+4=12

5x=12-4

5x=8

x=8/5

c)8x=40

x=40/8

x=5

d)x+4=9

x=9-4

x=5

e)2(x+4)=26

2x+8=26

2x=26-8

2x=18

x=18/2

x=9
