Answer 2

we chat I will tell you OK

-9=(-18)-2Y

We move all terms to the left:

-9-((-18)-2Y)=0

We calculate terms in parentheses: -((-18)-2Y), so:

(-18)-2Y

determiningTheFunctionDomain

-2Y+(-18)

We add all the numbers together, and all the variables

-2Y-18

Back to the equation:

-(-2Y-18)

We get rid of parentheses

2Y+18-9=0

We add all the numbers together, and all the variables

2Y+9=0

We move all terms containing Y to the left, all other terms to the right

2Y=-9

Y=-9/2

Y=-4+1/2
