Answer 2

To solve the equation $9x - (5x - 4) = 4x + 4$, follow these steps:

Step 1: Distribute the negative sign through the parentheses on the left side of the equation: $9x - 5x + 4 = 4x + 4.$

Step 2: Combine like terms on both sides of the equation: $4x + 4 = 4x + 4.$

Step 3: Subtract $4x$ from both sides of the equation to isolate the constant term: $4 = 4.$

Step 4: Since $4 = 4$, this equation is true for all values of $x$. In other words, there is no specific solution for $x$, and the equation holds true regardless of the value of $x$.

The solution to the given equation is that it is an identity, meaning that the equation is true for all real values of $x$.
