Answer:
Step-by-step explanation:
Just multiply the first equation by -1 and then add them together to find x. Should look something like
-2x - y = -7
5x + y = 9
--------------------
3x + 0 = 2
x = 2/3
Now back substitute using either equation to find y. I'll use the first:
2(2/3) + y = 7
4/3 + y = 7
y = 7 - 4/3 = 21/3 - 4/3 = 17/3
Answer:
x=2/3
y=17/3
Answer:

Step-by-step Explanation:
There are 52 weeks in a year. Total number of days she is expected to work would be 52 * 5 = 260 days.
Now we know she has 10 vacation days and 10 holidays. This translates 260 - 20 = 240 days
Now if she drives 35miles 5 days of the week, this means she dives 7 miles per day.
The total number of miles traveled is this 240 * 7 = 1680 miles
