Answer: 4 hours
Step-by-step explanation:
Let the number of hours that the repair take be represented by h.
Since the cost of Sam's car repair is $20 an hour plus $180 for parts and the total cost was $260, this can be formed into an equation as:
180 + 20h = 260.
20h = 260 - 180.
20h = 80
h = 80 / 20
h = 4
The repair took 4 hours

Answer:
x = 8
Step-by-step explanation:
-4x + 6(6 - 2x) = -7x - 36
-4x + 36 - 12x = -7x - 36
-16x + 36 = -7x - 36
<u> +36 +36</u>
-16x + 72 = -7x
<u>+16x +16x</u>
72 = 9x
divide by 9
<u><em>x = 8</em></u>
