Question

3. Reducir los términos semejantes para resolver las siguientes ecuaciones. ​

Answer 1

Respuestas:

a.

9x - 2x = 4 - 3

7x = 1

x = 1/7

b.

8m + 5m = -6 - 2

13m = -8

m = -8/13

c.

6w + 3w = 10 + 2

9w = 12

w = 12/9

w = 4/3

d.

12 -  4 = 5n + 8n

8 = 13n

n = 8/13

e.

7p + 3p = 5 - 14

10p = -9

p = -9/10

f.

8a - 5a = -10 - 3

3a = -13

a = -13/3

g.

6 + 4 = 4q - 2q

10 = 2q

q = 5

h.

3 - 4 = 5r - 2r

-1 = 3r

r = -1/3

i.

6 + 2 = 4y + 6y

8 = 10y

y = 8/10

y = 4/5

j.

14s + 7s = 4 + 10

21s = 14

s = 14/21

s = 2/3
