Answer is A, you should not do negatives on the other side, copy the same monomial on the other sides
So, you need to do the same operation to each side.
Start out by subtracting 3 from each side
1/4 (20x+8) = -3
Then, multiply both sides by 4
40x+8 = -12
Then, subtract 8 from each side
40x = -20
divide both sides by 40 and you get
x=-1/2

Arc KNL = 18x-6 + 5x+17
= 23x + 11
= 23*11 + 11
= 264</span>
