Answer: x = 4.
Explanation:
To determine the value of x in the expression 4x - 8 = x + 4, you can solve for x by isolating it on one side of the equation. Here's how to do it step by step:
1. Start with the equation:
4x - 8 = x + 4
2. To isolate the variable x on one side, you can subtract x from both sides of the equation to move the x term to the left side:
4x - x - 8 = x - x + 4
3. Simplify the equation:
3x - 8 = 4
4. Next, add 8 to both sides of the equation to isolate the 3x term:
3x - 8 + 8 = 4 + 8
5. Simplify further:
3x = 12
6. Now, to find the value of x, divide both sides of the equation by 3:
(3x) / 3 = 12 / 3
7. Simplify the division:
x = 4
So, the value of x in the equation 4x - 8 = x + 4 is x = 4.
