Answer 1

Respuesta:

4x / 33 + x = 1 / 3

4x = 1/3 ( 33 + x )

4x = 33 + x / 3

12x = 33 + x

12x - x = 33

11x = 33

x = 33/11

x = 3

4x / 15 - 6x + 28 / 5 = 0

4x / 15 - 2 ( 3x + 14 ) / 5 = 0

2 ( 2x / 15 - 3x + 14 / 5 ) = 0

2x / 15 - 3x + 14 / 5 = 0

2x - 3 ( 3x + 14 ) = 0

x = - 6

2x / 3 = 5x / 12 - 2

8x = 5x − 24

8x − 5x = − 24

3x = − 24

x = - 24 / 3

x = - 8

3x - 2x / 5 = 3x / 10 + 14

13x / 5 =  3x / 10 + 14

26x = 3x + 140

26x − 3x = 140

23x = 140

x = 140/23

4x - 3 / 5 - 4x / 3 = 2 ( x - 13 ) / 15

3(4x−3)−20x=2(x−13)

12x−9−20x=2x−26

−8x−9=2x−26

−9=2x−26+8x

−9=10x−26

−9+26=10x

17=10x

17/10 = x

x = 17/10
