x=4

Answer 3

To solve the equation, let's simplify and then solve for the value of x:

-x - 2 + 3*(x - 3) = 3(4 - x) - 3

Let's simplify the equation step by step:

First, distribute the 3 on the left side and the 3 on the right side:

-x - 2 + 3x - 9 = 12 - 3x - 3

Simplify both sides by combining like terms:

2x - 11 = 9 - 3x

Next, let's isolate the x terms on one side and the constant terms on the other side. Add 3x to both sides and add 11 to both sides:

2x + 3x = 9 + 11

Combine like terms:

5x = 20

To solve for x, divide both sides by 5:

x = 20/5

Simplify:

x = 4

Therefore, the solution to the equation is x = 4.
