The algebraic identity y + 15 ÷ 3 + 2 =72÷9 − 1 + y can be simplified to the following equation, which we know is true because of the Commutative Property.
A.

y + 8 = 8 + y
B.

y − 8 = 8 − y
C.

y + 7 = 7 + y
D.

y − 7 = 7 − y

Answer 1

Cancel y on both sides
\[\frac{ 15 }{ 3 }+2=\frac{ 72 }{ 9 }-1\]
Simplify
\[5+2=\frac{ 72 }{ 9 }-1\]
Simplify
\[5+2=8−1\]
\[7=8-1\]
\[7=7\]
