Answer 3

To simplify the expression 1,2(a-c)-(a-5c), you can use the distributive property and combine like terms. Here's how you can do it step by step:

1. Distribute the 1,2 to both terms inside the parentheses:

   1,2 * (a - c) - 1,2 * (a - 5c)

2. Multiply each term inside the parentheses by 1,2:

   (1,2 * a - 1,2 * c) - (1,2 * a - 1,2 * 5c)

3. Simplify each term inside the parentheses:

   (1/2 * a - 1/2 * c) - (1/2 * a - 5/2 * c)

4. Now, distribute the negative sign in front of the second set of parentheses:

   1/2 * a - 1/2 * c - 1/2 * a + 5/2 * c

5. Combine like terms:

   (1/2 * a - 1/2 * a) + (-1/2 * c + 5/2 * c)

6. Simplify further:

   0 + (4/2 * c - 1/2 * c)

7. Combine like terms again:

   0 + (2c - 1/2c)

8. Finally, simplify the expression:

   2c - 1/2c

So, the simplified expression is 2c - 1/2c.
