Answer 1

It seems like you've posted some mathematical equations, and you're looking for answers to these equations. Let's break them down and solve them step by step:

1. 2(3x - x) - 5 = 2x - 2x

   Start by simplifying both sides of the equation:

   2(2x) - 5 = 0

   Now, distribute the 2 on the left side:

   4x - 5 = 0

   Add 5 to both sides:

   4x = 5

   Finally, divide both sides by 4 to solve for x:

   x = 5/4 or 1.25

2. 5(2 - 2x) + 16 = 4x + 16

   Start by simplifying both sides of the equation:

   10 - 10x + 16 = 4x + 16

   Combine like terms on both sides:

   -10x + 26 = 4x + 16

   Now, move the 4x term to the left side by subtracting 4x from both sides:

   -10x - 4x + 26 = 16

   Combine like terms:

   -14x + 26 = 16

   Next, subtract 26 from both sides:

   -14x = -10

   Finally, divide both sides by -14 to solve for x:

   x = -10 / -14

   Simplify the fraction:

   x = 5/7

So, the solutions for the equations are:

1. For the first equation: x = 5/4 or 1.25
2. For the second equation: x = 5/7 or approximately 0.7143

It looks like the provided answers do not match the solutions to the equations. If you have any further questions or if there's something specific you'd like to know, please feel free to ask.
