Answer 2

The temperature in smalltown six hours ago was 11 F.

SOLUTION:

Given, current temperature in smalltown is 18 F.

Given that 18 F is 4 degrees less than twice the temperature that it was six hours ago.

We need to find what was the temperature six hours ago.

Let the temperature six hours ago be x.

Given that 18 F is 4 degrees less than twice the temperature that it was six hours ago.

Then, 2x - 4 = 18

2x = 18 + 4

2x = 22

x =
`(22)/(2)`

x = 11 F.

Hence, the temperature in smalltown, six hours ago was 11 F.
