Answer 1

Respuesta:

1. -x + 5x + 3 - 4 = x + 2    

4x + 3 - 4 = x + 2

3x = 3   x = 1

2. y - 44y = 18 - 15y

- 43y = 18 - 15y

28y = 18   y = - $\frac{18}{28}$   simplificando  y = -$\frac{9}{14}$  (el menos va en la línea)

3. 3v + 2 + 5v = 18 - 2v + 3v

8v + 2 = 18 + v

7v = 16   v = $\frac{16}{7}$

4. 35v + 5 = 21v + 15

14v = 10   v = $\frac{10}{14}$   simplificando  v = $\frac{5}{7}$

5. 50b + 5 + 3b = 58 + b

53b + 5 = 58 + b

52b = 53   b = $\frac{53}{52}$

6. 10z - 2 + 5 = 14 - 2z

10z + 3 = 14 - 2z

12z = 11   z = $\frac{11}{12}$

7. 9y + 5 + 3y = 149 + 5y

12y + 5 = 149 + 5y

7y = 144   y = $\frac{144}{7}$

8. 7u - 4 = 8u + 3 - 5u

7u - 4 = 3u + 3

4u = 7   u = $\frac{7}{4}$

9. 4z - 7z = 9 - 6z

- 3z = 9 - 6z

3z = 9   z = $\frac{9}{3}$ = 3

10. 8v + 3v = 5 - 8v + 2

11v = 7 - 8v

19v = 7   v = $\frac{7}{19}$

11. 10 - 3 + u = 5u - 2 + u

7 + u = 6u - 2

9 = 5u   u = $\frac{9}{5}$

12. w + 12 + 3w = 5 + 9w - 9

4w + 12 = - 4 + 9w

16 = 5w   w = $\frac{16}{5}$
