I need help please

Seiji and Gavin both worked hard over the summer. Together they earned a total of $525. Gavin earned $25 more
than Seiji.
(a) Write a system of equations for the situation. Use s for the amount Seiji earned and g for the amount Gavin
earned.
(b) Graph the equations of the system on the graph provided on the next page.
a. Note: Insert->Shape will allow you to add lines, draw dots, and otherwise insert shapes in both
Microsoft Word and LibreOffice. The graph should be big enough for you to easily plot points using
this method.
b. If you do not want to graph using the drawing tools built into Microsoft Word or LibreOffice you may
also print out, graph by hand, and scan the page. Please note it’s perfectly okay to upload multiple
files.
(c) Use your graph to estimate how much each person earned, and explain your results.

Answer:

Let the money Seiji got be x and Gavin, y.

Total is 425.

So, x + y = 425

Gavin got 25 more than Seiji.

So, y = x + 25

I will use substitution method.

Substitute y = x + 25 in x + y = 425.

x + x + 25 = 425

2x + 25 = 425

2x = 400

x=$200

So, x is Seiji and he got $200.

For Gavin, substitute x in the equation of y.

y = x + 25

y = 200 + 25

y = $225

So, y is Gavin and he got $225.

For the graph part, I don't know how to show you. Hope you will be able to do the rest by yourself. If you need help with graphing, you may use desmos.com.
