D C D C B are the correct answers in order
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
<u>Answer:</u>

.
<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:
Here the variables 
and 
are having negative powers. So to change these powers from negative to positive, we will take their reciprocals to get:
