For each example identify which property of the real numbers demonstrated:
Identity property; distrubitive property; associative property; additive inverse property; commutative property; multiplicative inverse property
*=multiplication
1. 5+x=x+5 (commutative property)
2. 2(7y)=(2*7)y (distributive property)
3. 6(z+2)=6z+12 (distributive property)
4. 7t-14=7(t-2) (distributive property)
5. 7+(r+4)=(7+r)+4 (assosiative property)
6. w(3)=3w (distributive property)
7. -3+3=0 (additive inverse property)
8. (1/8)*8=1 (multiplicative inverse property)
