Answer 1

Respuesta: 4w < 10 - 2

4w < 8

w = 8 / 4 = 2

4* 8 = 10 - 2

w = 5- 3

w = 2

2 + 3 = 5

5x - 20 + 6 = 5 - x

5x + x = 5 + 20 - 6

6x = 19

x = 19 / 6

x = 3.16666

4 ( - 9 - y ) = 5 ( - 7 - y )

- 36 - 4y = - 35 - 5y

- 4y + 5y = - 35 + 36

y = 1

1ra e: 5x = 9 - 1

5x = 8

x = 8 / 5

x = 1.6

8 + 1 = 9

2da e : 4x = 7 - 1

4x = 6

x = 6 / 4

x = 1.5

6 + 1 = 7
