<em>Hello there, and thank you for posting your question here on brainly.

</em>Short answer: x = -5
<em>
</em>Why?

The solution to this has a lot of steps. Subtract two from both sides. (2+7/x=3/5 --> 7/x=-7/5) Multiply both sides by x. (7/x=-7/5 --> 7=-7x/5) Multiply both sides by 5. (7=-7x/5 --> 35=-7x) Divide both sides by -7. (-5=x) x = -5

<em>Hope this helped you! ♥</em>

At the beginning of summer, Mark has $200 in savings and Ryan has $350. The brothers have mowing jobs set up for the summer. Bec
zepelin [54]

Answer:

m = 200 + 20j

r = 350 + 15j

Number of jobs is 30

<em></em>

Step-by-step explanation:

<u>Variable representation</u>

Let Mark's total earnings for moving be m

Let Ryan's total earnings for moving be r

Represent the number of jobs with j

<u>Setup equation</u>

Mark:

Initial\ Savings = 200

Rate = 20

So, the total savings is:

m = 200 + 20j

Ryan

Initial\ Savings = 350

Rate = 15

So, the total savings is:

r = 350 + 15j

<u>To get the number of jobs they save the same amount.</u>

We have:

m = r

Substitute values for m and r

200+20j = 350+15j

Collect Like Terms

20j - 15j = 350 - 200

5j = 150

Divide both sides by 5

j = \frac{150}{5}

j = 30

<em>Hence, the number of jobs is 30</em>
