2-(3x-8)
Essentially, that is 2-1(3x-8), people just don't write the 1
First, we can use the distributive property to get rid of the parenthesis.
2-1(3x-8) is the same as 2+(-1*3x)+(-1*-8)
We can simplify that to: 2-3x+8
Then, we just re-arrange the equation and do some addition: -3x+10
So when you simplify 2-(3x-8), you get -3x+10
As a way to check, you can substitute a value in for x and see if the two expressions get the same result.
In addition, when you are writing an expression, you always put the variables first, in alphabetical order.
