Practice Combining Like Terms with Negative Coefficients

1. Combine the like terms to create an equivalent expression:
   

   $$4z-(-3z) = $$

2. Combine the like terms to create an equivalent expression:
   

   $$-3k-(-8) + 2$$

3. Combine the like terms to create an equivalent expression:
   

   $$-n+(-3) + 3n+5$$

4. Combine the like terms to create an equivalent expression:
   

   $$-4r - 2r+5$$

5. Combine the like terms to create an equivalent expression:
   

   $$-k-(-8k)$$

6. Combine the like terms to create an equivalent expression:
   

   $$-12-6p-(-2)$$

7. Combine the like terms to create an equivalent expression:
   

   $$2r+1+(-4r)+7$$
