Identify the law that justifies each of the following statements:a,(2x + 3) + 5 = 2x + (3 + 5)b,2x + 5 + 3x = 2x + (3x + 5)c,If a + b = 0,then b = -a
Identify the law that justifies each of the following statements:
a,(2x + 3) + 5 = 2x + (3 + 5)
b,2x + 5 + 3x = 2x + (3x + 5)
c,If a + b = 0,then b = -a

Identify the law that justifies each of the following statements:a,(2x + 3) + 5 = 2x + (3 + 5)b,2x + 5 + 3x = 2x + (3x + 5)c,If a + b = 0,then b = -a
a. Associative law for addition
b. Commutative law for addition
c. Inverse law for addition.
