Answer:
x = 5
Step-by-step explanation:
I just solved the equation!
5 - 4(2-x) = 17
-4(2-x) = 12 (subtract by 5 on both sides)
2 - x = -3 (divide by 4 on both sides)
-x = -5 (subtract by 2 on both sides)
x = 5 (divide by -1 on both sides (two negatives cancel out!))

Answer: 100%
Step-by-step explanation:
Given the following :
Price of antique car in 2020 is 200% of its original price in 1980.
By what percentage did the price increase over this 40-year period?
Let the original price = x
x = price of car in 1980
Price of car in 2020 = 200% of x = 2x
Percentage increase in price is given by:
(increase / original price) × 100%
Increase = (price in 2020 - price in 1980)
[(Price in 2020 - price in 1980) / original price] * 100%
[(2x - x) / x] * 100%
[(2x - x) / x] * 100%
(x /x) * 100%
= 1 × 100%
= 100%
100x%
