2/3- (-8y) 9

Question

2/3 - negative 8y over 9

Answer 1

2/3 - (-8y)/9 = 6/9 + 8y/9 = (6 + 8y)/9

Answer 2

The order of operations follows: 

Parentheses
Exponents
Mult/Div
Add/Subt

There are a few ways to simplify, this is just one way. 

The negative sign outside the (-8y) can be thought of as (-1)(-8y). Let's "distribute" that into (-8y), and you know that a neg*neg = pos to give:

2/3 + (8y)(9)

Multiplication before addition/subtraction:

2/3 + 72y

This is the most simplified form of the expression since 2/3 is a constant term and 72y is a variable term, thus they are not like terms and cannot be combined beyond this.
