Answer: 20 = 5 × n ; n = 4
How do we know?
If the blue jar has 20 marbles, and the blue jar has 5 times as many as the red jar, and n is how many marbles are in the red jar then we can use this equation:
n × 5 = 20
So for the first portion of your question the answer would be: 20 = 5 × n
Now we have to solve for n:
20/5 = n
4 = n
So the answer to your second part would be: n = 4
26 goes into 50 once. so put a 1 on top of the 5. multiply the 1 by 26, which is 26. write 26 underneath the "50" in 503. 50-26 = 24. bring down the 3 so you now have 243. how many times can 26 go into 243 evenly? the answer is 9. so put a 9 on top of the 0. multiply the 9 by 26 and you get 234. so whatever 243 - 234 equals, thats your decimal

The answer is -10! Glade I could help!!
Id say |x|=5, that's my guess
