Answer:
x = 3
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 =

= 3
Therefore x = 3 is the answer.
