Answer 2

CORRECT ANSWER :

$\implies\sf \: x =\dfrac{1}{2}$

CORRECT QUESTION :

$\sf{\dfrac{9x-7}{3x + 5}= \dfrac{3x - 4}{x + 6}}$

STEP BY STEP EXPLANATION :

• ( cross multiplication )

$\sf{(9x-7)(x+6)=(3x-4)(3x+5)}$

• ( multiply binomial by binomial )

$\sf{9x}^{2} +47x-42={9x}^{2} +3x-20$

$\sf{81x}^{2} +47x-42={81x}^{2} +3x-20$

• Subtract 81x² from both sides.

$\sf{81x}^{2} +47x-42-81{x}^{2} ={81x}^{2} +3x-20-{81x}^{2}$

$\sf47x-42=3x-20$

$\sf{47x - 3x =42 - 20}$

$\sf44x =22$

$\sf \:x = \dfrac{22}{44} = \dfrac{1}{2}$
