Answer
Commutative Property of Addition:
$-7+3x$
Commutative Property of Multiplication:
$x(3)-7$
Work Step by Step
For any real numbers a, b, and c:
(i) Commutative Property of Addition: $a+b=b+a$
(ii) Commutative Property of Multiplication: $a\cdot b = b \cdot a$
Thus, using the properties above, the following expressions are equivalent to the given expression:
Commutative Property of Addition:
$-7+3x$
Commutative Property of Multiplication:
$x(3)-7$
