the correct answer should be (b) 6 is extraneous.
If you look at the second row of the solution you see (x-6) as a factor in one of the denominators. That's a problem: if 6 were a solution this denominator would become 0. But denominators being 0 is bad (undefined), so while 6 comes out of the algebraic manipulation as a solution, it is invalid, or extraneous.
-3 is a fine solution.
Solution: X=6
Detailed explanation:
In this problem we're asked to find "x" or the unknown.
The first step is to subtract 11x from both sides.
Next, subtract 79 from both sides.
To finish this off, divide both sides by -11.
Voila! There's our answer!

Answer:
27°C
Step-by-step explanation:
The temperature on February 9th 1934 = -15°C
The next day the temperature rose 42 degrees.
We need to find an expression for the temperature on February 10th.
February 10th temperature = -15 + 42
= 27°C
So, the temperature on February 10th is 27°C.
