Ok so assuming that the 'x' means multiply and not 'x' as in placeolder we do
PEMDAS
parenthaseees
exponents
multipilcation or division
additon or subtraction
parethasees simplify first
(8+7)=15
(9-3)=6
now we have
2x(15)-6/2x(6)
multiply
2x15=30
6/2x6=36/2=18
now we have
30-18
12
answer is 12

Let's solve this inequality!

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

Now, move 20 to the right, using the opposite operation:

Subtract:

Divide both sides by -1 to isolate x:
(Answer)
_____________
<em>Additional comment</em>
When we divide both sides of an inequality by a negative number, we flip the inequality sign.
