Solution:
Given:

The value of a car after t - years will depreciate.
Hence, the equation given represents the value after depreciation over t-years.
To get the rate, we compare the equation with the depreciation formula.

Hence,

Therefore, the value of this car is decreasing at a rate of 6%. The purchase price of the car was $16,300.
It’s 18x because 36 and 54 are both divisible by 18, and 18 can be divisible by 18 (making 1), resulting in 18 being the most common number between the numbers, whereas the ‘x’ is common between all 3 numbers and since the least amount of x is 1, the answer is just x without an exponent
3x-6=6(x+2)
3x-6=6x+12 3x-6x=6+12
-3x=18 X= 18/-3 X= -6 first number .
For second number you substitute x+2.
-6+2=-4
X + 0.5 + 3x - 2 = 3x + 1.5
X= 3.5
Putting the all x on the right side and distributing all the numbers on the left side
6y-10=y+25
subtract y from both sides
5y-10=25
add 10 to both sides
5y=35
divide both sides by 5
y=7
