1. First, distribute the positive sign inside the parentheses:
54 + x - 4 = x
2. Next, you can simplify the equation by moving all terms containing x to one side and constants to the other side:
x - x = 4 - 54
3. Subtract x from both sides:
0 = -50
Now, you have an equation with 0 on one side, which means there is no solution for x. The original equation 54 + (x - 4) = x has no solution.
