Commutative Property of Addition: $-7+3x$ Commutative Property of Multiplication: $x(3)-7$
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: $x(3)-7$
