Question

resuelva estas ecuaciones
a. 3 x = 6 x + 10
b. 12 = −4 x − 3 + 6 x
c. 5 x + 2 = −10
d. 4 x − 2 = 5 + 3 x – 6
e. 3 − 2 x = 1

Answer 1

Respuesta:

a. x = -10/3

b. x = 15/2

c. x = -12/5

d. x = 1

e x = 1

Explicación paso a paso:

a. 3 x = 6 x + 10

-10 = 6x - 3x

-10 = 3x

-10/3 = x

b. 12 = −4 x − 3 + 6 x

12 + 3 = -4x + 6x

15 = 2x

15/2 = x

c. 5 x + 2 = −10

5x = -10 - 2

5x = -12

x = -12/5

d. 4 x − 2 = 5 + 3 x – 6

4x - 3x = 5 - 6 + 2

x = 1

e. 3 − 2 x = 1

3 - 1 = 2x

2 = 2x

2/2 = x

1 = x
