Answer 3

To solve the equation 5x - 1 = 4(x + 2) - (9 - x), we need to simplify and then isolate the variable x.

Let's start by simplifying the equation step by step:

5x - 1 = 4(x + 2) - (9 - x)

First, let's simplify the expressions within the parentheses:

5x - 1 = 4x + 8 - (9 - x)

Next, let's remove the parentheses by distributing the numbers:

5x - 1 = 4x + 8 - 9 + x

Combine like terms:

5x - 1 = 5x - 1

Now, observe that both sides of the equation are the same. This indicates that the equation is an identity, meaning that the equation is true for all values of x. In other words, any value of x would satisfy this equation.

Therefore, the solution to the equation is all real numbers.
