Answer:
9 3/4! I hope this helps!
Step-by-step explanation:
The combined total profit is (17x + 2502) dollars
<em><u>Solution:</u></em>
Profit for each Mp3 player = $ 35
Profit for each DVD player = $ 18
Let x be the number of MP3 players sold last week
Number of MP3 players = x
Last week, Techwiz sold a combined total of 139 MPS and DVD players
Total number of mp3 and dvd sold = 139
Number of DVD player = 139 - x
<em><u>Write an expression for the combined total profit (in dollars) Techwiz made from MP3 and DVD players last week.</u></em>
Combined total profit = Number of MP3 players x Profit for each Mp3 player + Number of DVD player x Profit for each DVD player

Thus the combined total profit is (17x + 2502) dollars
This seems like a lot more work than it is, but here we go
Simplifying<span>8 + -2y = 3y + -2
Reorder the terms:
8 + -2y = -2 + 3y
Solving
8 + -2y = -2 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
8 + -2y + -3y = -2 + 3y + -3y
Combine like terms: -2y + -3y = -5y
8 + -5y = -2 + 3y + -3y
Combine like terms: 3y + -3y = 0
8 + -5y = -2 + 0
8 + -5y = -2
Add '-8' to each side of the equation.
8 + -8 + -5y = -2 + -8
Combine like terms: 8 + -8 = 0
0 + -5y = -2 + -8
-5y = -2 + -8
Combine like terms: -2 + -8 = -10
-5y = -10
Divide each side by '-5'.
y = 2
Simplifying
y = 2</span>
I think it’s either a or c I’m not sure but I’m going for c please lmk if I’m wrong
