Hmm, it looks like it could be commutative property of multiplication.
The order of the expression is different.
4(2+3)=
4(5)=20
(2+3)4=
(5)4= 20
4+3 = 7
This is the amount of dollars spent each day
25/7 = 3 4/7
This means the money will last for 3 days.
X=2
-4 on both sides
4=2x
divide by 2 on both sides
X=2
