To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.
![8c = 5c + 21\\8c - 5c = 5c - 5c + 21\\3c = 21](https://tex.z-dn.net/?f=8c%20%3D%205c%20%2B%2021%5C%5C8c%20-%205c%20%3D%205c%20-%205c%20%2B%2021%5C%5C3c%20%3D%2021)
Then, divide by 3 on each side.
![3c = 21\\3c /3 = 21/3\\c = 7](https://tex.z-dn.net/?f=3c%20%3D%2021%5C%5C3c%20%2F3%20%3D%2021%2F3%5C%5Cc%20%3D%207)
So, c = 7.
Answer:
1/2, 2/4.
Step-by-step explanation:
2/4 is one fraction because there are 2 bananas out of 4 pieces of fruit.
This can be simplified to 1/2.
Let m = the amount books Rachel sold on Monday.
then t = the amount books Rachel sold on Tuesday.<span>
then w = </span><span>the amount books Rachel sold on Wednesday.
On Tuesday she sold twice as she did on Monday.
t = m * 2
On Wednesday she sold 6 fewer books than she did on Tuesday
w = t - 6
Now for the fun.
t = m * 2
w = t - 6
Substitute t for real value
w = m * 2 - 6
Now solve for m.
w - 6 = m * 2 <-- Transpose the 6
(w-6)/2 = m <-- Transpose the 2.
m = (w-2)/2 < The Law of Reflexive Property of Equality</span>
