Question

me ayudan con estas ecuación de primer grado ​

Answer 1

Respuesta:

e)

6x = 42

x = 42/6

x = 7

f/

8x = 88

x = 88/8

x = 11

g)

x/3 = 9

x = 9 . 3

x = 27

h)

x/8 = 7

x = 7 . 8

x = 56

i)

5x - 5 = 2x + 16

5x - 2x = 16 +5

3x = 21

x = 21/3

x = 7

j)

5x + 10 = 2x + 40

5x - 2x = 40 - 10

3x = 30

x = 30/3

x = 10

k)

4x - 3 = 3x + 2

4x - 3x = 2 + 3

1x = 5

x = 5

l)

6x - 6 = 5x + 5

6x - 5x = 5 + 6

1x = 11

x = 11
