Answer 1

Respuesta:

1.

$C_{3x} = 75$

90 - 3x = 75

90 - 75 = 3x

  15 = 3x

   5 = x

2.

$C_{\beta } = 5\beta$

90 - $\beta = 5 \beta$

90 = $6\beta$

15 = $\beta$

3.

C$S_{110}$= 180 - 110 = 70

$C_{70} = 90 - 70 = 20$

4.

$S_{x} = 4x$

180 - x = 4x

 180 = 5x

  36 = x

5.

2x + 3x = 90

5x = 90

x = 18

6.

x + 30 3x 0 90

 4x = 60

  x = 15

7.

4x + x = 90

5x = 90

 x = 18

8.

4x + x = 90

5x = 90

x= 18
