The answer to that is A) 1
Put X-4 to where Y is in the first equation. So;
X-4= -X-6
Then solve to find X;
Add 6 to both sides;
X+2=-X
Subtract X from both sides;
2=-X-X
2= -2X
Divide both side by -2;
-1=X
Answer:

Explanation:
To solve the question, first find the number of miles Rachel power walked.
She walked
2
3
5
or
2.6
miles a day for seven days. Multiply seven days by
2.6
to find the total number of miles Rachel power walked that week.
2.6
⋅
7
=
18.2
Next, find the number of miles Rachel jogged.
She jogged
5.75
miles a day for four days. Multiply
4

4
=
23
Rachel power walked 18.2 miles and jogged 23 miles. Add the two values up to find the total number of miles that she power walked and jogged.
18.2
