Evaluate 5x−3/2x−1 = 4/3 ^3

Answer»

QUESTION:

Evaluate

\frac{5x - 3}{2x - 1}  =  {  \big(\frac{4}{3} \big) }^{3}

Step-by-step EXPLANATION:

\frac{5x - 3}{2x - 1}  =  {  \big(\frac{4}{3} \big) }^{3}

\implies 5x - 3 = 2x - 1[{ \big( \frac{4}{3} }^{3} \big) ]

\implies 5x - 3 = 2x - 1 \big[ \frac{64}{27}  \big]

5x - 3 = 128 -  \frac{64}{27}

5x - 3 =  \frac{3456x - 64}{27}

135x - 3 = 3456x - 64

3321x - 61 = 0

3321x = 61

\boxed{x =  \frac{61}{3321} }
