Linear equations do have extraneous solutions
The greatest common factor of both numbers is 6 so you would take out that 6 since both of those numbers can be multiplied by it. So, your answer would be 6(5x+1) and if you multiply that 6 back in, you will go back to the original equation.

Answer:
$24,000
Step-by-step explanation:
1. Find what 20% of 30,000 is.
20% x 30,000 = 6,000
2. The problem says the cost of a new car is 20% greater than a used car. Subtract the 6,000 from 30,000 to get the cost of the used car.
30,000 - 6,000 = 24,000
3. The cost of the used car is $24,000
