Answer: x=6,y=4
Explanation:
x + y = 10 x − y = 2
Add both equations together.
x + x + y − y = 10 + 2
2 x = 12∣ : 2
x = 6
Sub the result into any of the two equations for x
6 + y = 10∣− 6
y = 4

Answer:
<h2>To accomplish his demands, he must accept 4 hours jobs or more than 4 hours jobs.</h2>
Step-by-step explanation:
We know that
Deepak charges $30 for each job plus $15 per hour, this means that the initial fixed fee is $30, and then he charges a variable fee of $15 per hour. This is expressed like
Where represents hours.
Now, if we only accepts jobs that pay at least $90, this means that the minimum fee is $90 and greater than $90. So, the whole expression is
Then, we solve for
Therefore, to accomplish his demands, he must accept 4 hours jobs or more than 4 hours jobs.
