Complete the following solution by filling in the missing statements and reasons.

Statements Reasons
1-2/3(4-5x)=5 Given
3-2(4-5x)=15 ?
? ?
10x-5=15 Simplify
10x=20 ?
x=2 Division Property

I need help on filling out the question marks in this proof. Also in 1-2/3(4-5x)=5 (the first statement) the 2/3 is a fraction not division.
