Answer:
x = 3
Step-by-step explanation:
The initial equation is:
3x + 8 = 7x - 4
To solve the equation, we can add 4 to both sides:
3x + 8 + 4 = 7x - 4 + 4
3x + 12 = 7x
Then, we can subtract 3x from both sides:
3x + 12 - 3x = 7x - 3x
12 = 4x
Finally, we can divide by 4 as:
12/4 = 4x/4
3 = x
Therefore, the answer is x = 3
