Answer:
Explanation:
if a(b + c) then ab + ac Distributive property
if a = b then b = c and a = c Transitive property
if a = b then a * c = b * c multiplication property
if a = b then a - c = b - c subtraction property
if a = b then a/b = b/c division property
if a = b then b = a symmetric property
if a = b then b can be substituted
for a in any expression substitution property
if a = b then a + c = b + c addition property
