Answer 1

Explicación paso a paso:

b)

3.x + 7 = 3 + 5.x

7 - 3 = 5.x - 3.x

4 = 2.x

4/2 = x

f)

2.x - 5.(1-3.x) = 1 - 3.(1-2.x)

2.x - 5 + 15.x = 1 - 3 + 6.x

17.x - 5 = -2 + 6.x

17.x - 6.x = -2 + 5

11.x = 3

x = 3/11

h)

6.y - 5.(1+2.y) = 3+ 2.(1-y)

6.y - 5 - 10.y = 3 + 2 - 2.y

- 4.y - 5 = 5 - 2.y

- 5 - 5 = -2.y + 4.y

-10 = 2.y

-5= y
