2)  Given: (2x 3) = 5x 4, solve for x:
Statement  Reason 

(2x 3) = 5x 4   2x + 3 = 5x 4  Distributive Law  3x + 3 = 4  Addition Property of Equality  3x = 7  Subtraction Property of Equality  x = ^{7}/_{3}  Division Property of Equality 

3)  Given: 3x = 3(x 3), solve for x:
Statement  Reason 

3x = 3(x 3)  Given  3x = 3x 9  Distributive Law  6x = 9   x = ^{3}/_{2}  Division Property of Equality
