Answer:
Step-by-step explanation:
3x+y=2............(1)
4y=12-12x........(2)
Making y as subject in (1) and substitute in (2)
y = 2 - 3x......(3)
4(2 - 3x) = 12-12x
8 - 12x = 12 - 12x
12x - 12x = 12- 8
0 = 4
So no solution since variable cancelled out

Answer:
$66,092.50
Step-by-step explanation:
In 1988, the car cost $17,000
Annual inflation over this period was 3.54% from 1988 to 2017
After adjusted for inflation, $17,000.00 in 1978 is equal to $66,092.50 in 2017
Therefore, the cost of that car in 2017 is closest to $66,092.50
