18000 represents the price of the new car.
The value of the car in 6 years can be found by substituting 6 for the variable t, as follows:
In 6 years, it will be worth around $8359.27.
The equation for the car worth $20000 is this:
In 6 years, the other car will be worth $7542.99, so the car worth $18000 will have more value in 6 years.

Answer:
(-2 ,3)
Step-by-step explanation:
Step 1: Rewrite first equation
x = 4 - 2y
-2x + y = 7
Step 2: Substitution
-2(4 - 2y) + y = 7
Step 3: Solve <em>y</em>
-8 + 4y + y = 7
-8 + 5y = 7
5y = 15
y = 3
Step 3: Plug in <em>y</em> to find <em>x</em>
x + 2(3) = 4
x + 6 = 4
x = -2
Answer z=2
