X=22, because (2x-5)+29+x=90-> 3x+24=90-> 3x=66-> x=22
S/2 + 8 = 54
To find out the cost of the spikes, we must isolate the variable.
first, subtract 8 from both sides.
S/2 +8 = 54
-8. -8
Now we have
S/2 = 46
now, to find out what s is on its own, we must multiply by the recipricle of S/2. if that doesn't make sense to you, just think of it as cancelling the division by multiplying by 2.
s/2 = 46
*2. *2
s = 92
The spikes cost $92.

Step-by-step explanation:
Ok friend I think I can help you out here!
So this Wiliam fellow sure has issues. But if you think about it 4 and 6 make 24! So here we go! 4 days back medicine, 6 days asthma, 8 days back medicine, 12 days asthma, 12 days back medicine, 18 days asthma, 16 days back, now from here it was 4, 6 : 8, 12 : 12: 18 and now we have the final week which is 24 back and 24 asthma so they match up. I hope this helps and if confused draw on a piece on paper. Draw 4 boxes and 6 below them circle them and draw a line to show they are a pair and keep going soon they will be on day 24 which is matched up! Please draw this out to understand it will really help! Have a great day soon to be Einstein!
