Question

Realice las siguientes ecuaciones:
*(47+ X) = 3 (X + 11)
* 3 (4X - 1) =3 (X + 9)
* 5 (2X - 1) + 3 (X - 2) = 10X - 5
* 3X + 2 (4X- 1) = X + 18

Answer 1

Respuesta:

1.   3 (4x -1) = 4 (3x + 3)

12x – 3 = 3x + 9  

12x – 3x = 9 + 3

9x = 12  

X = 12/9

X = 4/3

 X = 1, 3

2. (47 + x) = 3 (x + 11)

47+ x = 3x + 33

-3x + x = -47 + 33

-2x= -14  

X= - 14/-2

x=7

3. 5 (2x – 1) +3 (x- 2) = 10x -5

10x – 5 + 3x – 6 = 10x – 5

3x = 7  

X = 7 / 3  

X= 2, 3

4. 3x + 2 (4x -1) = x +18

3x + 8x – x = 18 + 2

10x = 20  

X = 20/10

     X= 2
