Respuesta :

20x + 12 = 14x +30
20x - 14x = 30 - 12
6x = 18
6x/6 = 18/6
x=3

Answer:

x = 3

Step-by-step explanation:

The given equation is 4(5x+3) = 14x + 30

20x + 12 = 14x + 30     [ Distributive rule ]

20x - 14x + 12 = 14x - 14x + 30  [Subtraction of 14x on both the side of the                   equation ]

6x + 12 = 30

6x + 12 - 12 = 30 - 12   [ subtraction of 12 on both the sides ]

6x = 18

x = [tex]\frac{18}{6}[/tex]

  = 3

Therefore x = 3 is the answer.
