Answer:

idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want

Step-by-step explanation:

Let's solve for x.

6x+7y=13x

Step 1: Add -13x to both sides.

6x+7y+−13x=13x+−13x

−7x+7y=0

Step 2: Add -7y to both sides.

−7x+7y+−7y=0+−7y

−7x=−7y

Step 3: Divide both sides by -7.

−7x

−7

=

−7y

−7

x=y

Sindrei [870]

Answer:

- Yes, They agree

Step-by-step explanation:

Do Rachel and Dylan argree?

- Yes, They agree

Prove your answer using the values of the ratio.

100 of your friends listen to it

- Total Number = 100

Rachel said the ratio of the number of the people who liked the playlist to the number of people who did not like the playlist is 75:25.

The ratio can be simplifies further by diving all through by 25;

75/25  : 25/25

3 : 1

Dylan said that for every three people who liked the playlist, one person did not.

This simplifies to 3 : 1.

Same thing with what rachel said, so they both agree
