Answer 2

To solve the equation 13 - 3(2x + 5) = x - 16, you'll need to follow these steps:

1. Distribute the -3 on the left side of the equation:

13 - 3 * 2x - 3 * 5 = x - 16

2. Perform the multiplications:

13 - 6x - 15 = x - 16

3. Combine like terms on both sides of the equation:

(13 - 15) - 6x = x - 16

-2 - 6x = x - 16

4. Move the x terms to one side of the equation and the constants to the other side by adding 6x to both sides:

-2 - 6x + 6x = x - 16 + 6x

-2 = 7x - 16

5. Now, add 16 to both sides to isolate the variable x:

-2 + 16 = 7x - 16 + 16

14 = 7x

6. Finally, divide both sides by 7 to solve for x:

14 / 7 = 7x / 7

2 = x

So, the solution to the equation is x = 2.
