Answer 1

Respuesta:

a.

7(x - 5) - x = 3

7x - 35 - x = 3

6x - 35 = 3

6x = 38

x = 19/3

b.

-3(2x - 5) - 5x = 3x

-6x + 15 - 5x = 3x

-11x + 15 = 3x

14x = 15

x = 15/14

c.

7(x - 2) - 6x + 1 = 3 - 4x

7x - 14 - 6x + 1 = 3 - 4x

x - 13 = 3 - 4x

5x = 16

x = 16/5

d.

4x + 2(2x - 5) = (x - 3) - (8 - x)

4x + 4x - 10 = x - 3 - 8 + x

8x - 10 = 2x - 11

6x = -1

x = -1/6
