Answer:
x=4
Explanation:
To find the value of x in equation 3x + 1 = x + 9, we need to solve for x.
First, we can subtract x from both sides of the equation: 3x + 1 - x = x + 9 - x
This simplifies to: 2x + 1 = 9
Next, we can subtract 1 from both sides of the equation: 2x + 1 - 1 = 9 - 1
This simplifies to 2x = 8
Finally, we can divide both sides of the equation by 2: 2x / 2 = 8 / 2
This simplifies to: x = 4
So the value of x in equation 3x + 1 = x + 9 is 4.
