What is the value of x when 14x + 8 = 3x +30?

The answer: x=2; Explanation: The key goal to these algebraic questions is to seperate "x" on to one side. Then subtract 3x from both sides of the equation resulting in 11x+8 = 30. Then subtract 8 from both sides resulting in 11x = 22. Finally, divide 11 to both sides and the resulting answer is x = 2.
