Debbie gave 1/5 of her candies to her sister. Then, she
had to give X of what she had left to her brother. Now
she only has 21 candies left. How many candies did she
have in the beginning? Pls hurry!

im not forsure  but maybe 15

Step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

the correct answer is c) 2.
