Question

Resolver las siguientes ecuaciones
5x + 3 = x − 7 + 4x
e) −4 + 2x = 5x + 8
f) −x + 6 + 3x = 6 − 2x
g) 2. (x + 4) − 5x = 23
h) 9 − 3. (x − 2) = x − 1
i) 4. (3 − 2x) + 3x = 2. (3 − x)

Answer 1

Respuesta:

d) 5x + 3 = x − 7 + 4x

5x + 3 = x - 7 + 4x

0x = -10

x = 0

e) −4 + 2x = 5x + 8

-4 - 8 = 5x - 2x

-12 = 3x

-4 = x

f) −x + 6 + 3x = 6 − 2x

-x + 2x + 3x = 6 -6

4x = 0

x=0

g) 2. (x + 4) − 5x = 23

2x + 8 - 5x =23

-3x = 23 - 8

-3x = 15

x = -5

h) 9 − 3. (x − 2) = x − 1

9 - 3x + 6 = x - 1

-3x - x = -1 -9 -6

-4x = -16

x = 4

i) 4. (3 − 2x) + 3x = 2. (3 − x)

12 - 8x + 3x = 6 - 2x

-8x + 3x + 2x = 6 - 12

-3x = - 6

x = 2

Answer 2

Respuesta:

Explicación pd) 5x + 3 = x − 7 + 4x

5x + 3 = x - 7 + 4x

0x = -10

x = 0

e) −4 + 2x = 5x + 8

-4 - 8 = 5x - 2x

-12 = 3x

-4 = x

f) −x + 6 + 3x = 6 − 2x

-x + 2x + 3x = 6 -6

4x = 0

x=0

g) 2. (x + 4) − 5x = 23

2x + 8 - 5x =23

-3x = 23 - 8

-3x = 15

x = -5

h) 9 − 3. (x − 2) = x − 1

9 - 3x + 6 = x - 1

-3x - x = -1 -9 -6

-4x = -16

x = 4

i) 4. (3 − 2x) + 3x = 2. (3 − x)

12 - 8x + 3x = 6 - 2x

-8x + 3x + 2x = 6 - 12

-3x = - 6

x = 2
