Solve 4/x-4=x/x-4-4/3 for x and determine if the solution is extraneous or not

4vir4ik [10]

<u>Answer:</u>

x = 4 (extraneous solution)

<u>Step-by-step explanation:</u>

$\frac { 4 } { x - 4 } = \frac { x } { x - 4 } - \frac { 4 } { 3 } \\ \frac { 4 } { x - 4 } - \frac { x } { x - 4 } = - \frac { 4 } { 3 } \\ \frac { 4 - x } { x - 4 } = - \frac { 4 } { 3 } \\ 3 ( 4 - x ) = - 4 ( x - 4 ) \\ 1 2 - 3 x = - 4 x + 1 6 \\ 4 x - 3 x = 1 6 - 1 2 \\ x = 4 \\$

This solution is extraneous. Reason being that even if it can be solved algebraically, it is still not a valid solution because if we substitute back $x=4$ , we will get two fractions with zero denominator which would be undefined.

7/√10-√3<br> plss faast very urgent

Bogdan [553]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Here's the solution :

$\dfrac{7}{ \sqrt{10 } - \sqrt{ 3} }$

$\dfrac{7}{ \sqrt{10} - \sqrt{ 3} } \times \dfrac{ \sqrt{10} + \sqrt{3} }{ \sqrt{10} + \sqrt{3} }$

$\dfrac{7( \sqrt{10} + \sqrt{3} )}{( \sqrt{ 10}) {}^{2} - ( \sqrt{ {3}})^{2} }$

$\dfrac{7 (\sqrt{10} + \sqrt{3}) }{10 - 3}$

$\dfrac{7( \sqrt{10} + \sqrt{3} )}{7}$

$\sqrt{10} + \sqrt{3}$
