Question

3m-3(m-n)6x-5a+2x-4a-(m+k)+2(m+k)

Answer 1

3m-3(m-n) = 3m - 3m + 3n = 3n

6x-5a+2x-4a = 8x - 9a

-(m+k)+2(m+k) = - m - k + 2m + 2k = m + k

Answer 2

3m-3(m-n)=3m-3m+3n=3n

6x-5a+2x-4a=8x-9a

-(m+k)+2(m+k)=-m-k+2m+2k=m+k

Так?

Answer 3

To simplify the given expression, let's combine like terms and perform the operations step by step:

1. Distribute the "-3" in the expression "3(m-n)": 3m - 3m + 3n

2. Combine like terms: (3m - 3m) will cancel out, leaving us with: 3n

3. Combine "6x" and "2x": 6x + 2x = 8x

4. Combine "-5a" and "-4a": -5a - 4a = -9a

5. Combine "(m+k)" and "2(m+k)": (m + k) + 2(m + k) = m + k + 2m + 2k

6. Combine "m" terms and "k" terms separately: (m + 2m) + (k + 2k) = 3m + 3k

Now, let's put everything together:

3m - 3(m - n) + 6x - 5a + 2x - 4a - (m + k) + 2(m + k)

After combining like terms and simplifying, the final simplified expression is:

3n + 8x - 9a + 3m + 3k

So, the simplified expression is: 3n + 8x - 9a + 3m + 3k
