Answer 1

Resposta:

Explicação passo-a-passo:

Answer 2

e)

4x - 10 = 2x + 2

4x - 2x = 2 + 10

2x = 12

x = 12 / 2

x = 6

f)

4x - 7 = 8x - 2

4x - 8x = - 2 + 7

- 4x = 5

x = 5 / (- 4)

x = - 1,25

g)

2x + 1 = 4x - 7

2x - 4x = - 7 - 1

- 2x = - 8

x = - 8 / (- 2)

x = 4

h)

9x + 9 + 3x = 15

9x + 3x = 15 - 9

12x = 6

x = 6 / 12

x = 0,5

i)

16x - 1 = 12x + 3

16x - 12x = 3 + 1

4x = 4

x = 4 / 4

x = 1

j)

3x - 2 = 4x + 9

3x - 4x = 9 + 2

- 1x = 11

x = 11 / (- 1)

x = - 11

k)

5x - 3 + x = 2x + 9

5x + x - 2x = 9 + 3

4x = 12

x = 12 / 4

x = 3
