Answer 1

Respuesta:

1. x+2 = 5     2. y-4 = 6      3. 8-z = 9          

x = 5-2           y = 6+4           z = 9+8

x = 3               y = 10                z = 17

 

mejor te mando por imagen lo que faltan des de el cuatro .

 

Answer 2

Respuesta:

Aca tenes!! Espero que te sirva :)

1.

$x + 2 = 5 \\ x = 5 - 2 \\ x = 3$

2.

$y - 4 = 6 \\ y = 6 + 4 \\ y = 10$

3

$8 - z = 9 \\ - z = 9 - 8 \\ z = - 1$

4.

$10 - x = 12 \\ - x = 12 - 10 \\ -x = - 2$

5.

$2x - 3 = 5 \\ 2x = 5 + 3 \\ x = 8 \div 2 \\ x = 4$

6.

$3y + 2 = 11 \\ 3y = 11 - 2 \\ y = 9 \div 3 \\ y = 3$

7.

$9x - 6 = 18 \\ 9x = 18 + 6 \\ x = 24 \div 9 \\ x = \frac{8}{3}$

8.

$5x + 7 = 3 \\ 5x = 3 - 7 \\ x = - \frac{4}{5}$

9.

$1 - 4w = 9 \\ - 4w = 9 - 1 \\ w = 8 \div ( - 4) \\ w = - 2$

10.

$2 - 7z = 13 \\ - 7z = 13 - 2 \\ z = - \frac{11}{7}$

11.

$8x - 6 = 6x + 4 \\ 8x - 6x = 4 + 6 \\ 2x = 10 \\ x = 10 \div 2 \\ x = 5$

12.

$12 + 7x = 2x + 22 \\ 7x - 2x = 22 - 12 \\ 5x = 10 \\ x = 2$

13.

$9 - 8y = 27 - 2y \\ - 8y + 2y = 27 - 9 \\ - 6x = 18 \\ x = 18 \div ( - 6) \\ x = 3$

14.

$2z + 9 = z + 1 \\ 2z - z = 1 - 9 \\ z = - 8$

15.

$3w - 3 = 4w + 11 \\ 3w - 4w = 11 + 3 \\ - w = 14 \\ w = - 14$

16.

$10x + 21 = 15 - 2x \\ 10x + 2x = 15 - 21 \\ 12x = - 6 \\ x = - \frac{6}{12} \\ x = - \frac{1}{2}$

17.

$21x - 3 = 3x + 6 \\ 21x - 3x = 6 + 3 \\ 18x = 9 \\ x = \frac{9}{18} \\ x = \frac{1}{2}$

18.

$11y - 5y + 6 = - 2 - 9y \\ 6y + 9y = - 2 - 6 \\ 15 y = - 8$
