=

=

= 54
You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x
2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
B and D
Hope this helps(just for word count lol)
7 + 2p = p
subtract 2p on both sides. it now leaves you with:
7= -p
divde both sides by -1.
-7 = p
