Answer:
The car would have to sell for $20,000
Step-by-step explanation:
You would subtract x from each side. It would then be 3y=-x-15. Then you would divide all of the equation by 3. Your final answer would be y=-3x-5.
Factor using the difference of squares.
a^2-b^2 = (a+b)(a-b)
100n^2-1
(10n+1)(10n-1)
Final answer: (10n+1)(10n-1)
