What is true about the solution above.
Masja [62]

ANSWER

x =  \pm \sqrt{3}

and they are actual solutions.

EXPLANATION

The given equation is:

\frac{ {x}^{2} }{2x - 6}  =  \frac{9}{6x - 18}

Cross multiply

{x}^{2} (6x - 18) = 9(2x -6 )

This implies;

{x}^{2} (6x - 18) - 9(2x - 6) = 0

3{x}^{2} (2x - 6) - 9(2x - 6) = 0

Factor

(3 {x}^{2}  - 9)(2x - 6) = 0

3 {x}^{2}  - 9 = 0 \: or \: 2x - 6= 0

3 {x}^{2}   = 9 \: or \: 2x  = 6

{x}^{2}   = 3\: or \: x  = 3

{x}  =  \pm \sqrt{3} \: or \: x  = 3

The domain of the given equation is

x \ne3

Therefore the actual solutions are

x =  \pm \sqrt{3}

NB: x=3 is not in the domain of the given equation. It cannot be an extraneous solution.

In February, Paul's electric bill was three dollars more than one-half his gas bill. If the electric bill was ninety-two dollars
Lostsunrise [7]
Let us assume the gas bill of Paul in February = x dollars
Then
Electric bill of Paul for the month of February = (x/2) + 3
Amount of Electricity bill of Paul for the month of February = $92
then we can write the equation as
(x/2) + 3 = 92
x/2 = 92 - 3
x/2 = 89
x = 89 * 2
   = 178 dollars
So the gas bill of Paul in February is $178. I hope this is the answer you were looking for.
