Answer 2

Sure, I'd be happy to help you with these math problems:

1. 2x - 2: To simplify this expression, combine the like terms. There's only one term with 'x' in it, which is 2x. So the simplified expression is: 2x - 2

2. 6x - 2x + 1: Again, combine the like terms in this expression: 6x - 2x + 1 (6x - 2x) + 1 4x + 1

3. 5 - (2/5): To subtract fractions, you need to have a common denominator. In this case, the common denominator for 5 and 2/5 is 5. So, rewrite 5 as a fraction with a denominator of 5: 5 = 25/5 Now, subtract the fractions: 25/5 - 2/5 = (25 - 2) / 5 = 23/5

So, the answers to the problems are:

1. 2x - 2
2. 4x + 1
3. 23/5 or 4.6 (in decimal form)
