Answer 2

Explicação passo-a-passo:

A)

1 - 3x - 5 - 4x = 6 - 7

- 3x - 4x = 6 - 7 - 1 + 5

- 7x = 3

-x = 3/7

-x (-1) = 3/7 (-1)

x = -3/7

B)

1 - 43x = 24x + 361

- 43x - 24x = 361 - 1

- 67x = 360

- x = 360/67

-x (-1) = 360/67 (-1)

x = - 360/67

C)

1 - 7x - 3 + 6 = 2x - 2

- 7x - 2x = - 2 - 1 + 3 - 6

- 9x = - 6

- x = - 6/9

- x = - 2/3

- x (-1) = - 2/3 (-1)

x = 2/3

D)

1 - x - 4 + 6x = 45

- x + 6x = 45 - 1 + 4

5x = 48

x = 48/5
