Answer 1

Answer:

$\bold{\boxed{\boxed{ ❲\frac{4x - 3}{2x + 1}❳ - 10 (\frac{2x + 1}{4x - 3} ) = 3}}}$

$❲ 2x+14x−3 ❳−10( 4x−3 2x+1)=3$

$\bold{( \frac{4x - 3}{2x + 1} ) - 10 (\frac{2x + 1}{4x - 3} ) = 3}</p><p>⟹( 2x+14x−3)−10( 4x−32x+1 )=3$

⟹$\bold{\frac{ {(4x - 3)}^{2} - 10 {(2x + 1)}^{2} }{(2x + 1)(4x - 3)} = 3}⟹ (2x+1)(4x−3)(4x−3) 2−10(2x+1) 2 =3$

$\bold⟹(16 {x}^{2} - 24x + 9) - 10(4 {x^{2} + 4x + 1)}$

$⟹(16x 2 −24x+9)−10(4x2 +4x+1)$

$\bold{= 3(8 {x}^{2} - 6x + 4x - 3)}=3(8x </p><p>2−6x+4x−3)$

$\bold{16 {x}^{2} - 24x + 9 - 40 {x}^{2} - 40x - 10}16x 2 −24x+9−40x 2−40x−10$

$\bold{ = 24 {x}^{2} - 18x + 12x - 9}=24x </p><p>2−18x+12x−9$

$\bold{⟹- 24 {x}^{2} - 64x - 1 = 24 {x}^{2} - 6x - 9}⟹−24x 2 −64x−1=24x 2 −6x−9$

$⟹\bold{- 24 {x}^{2} - 24 {x}^{2} - 64x + 6x - 1 + 9 = 0}⟹−24x 2−24x 2−64x+6x−1+9=0$

$⟹\bold{- 48 {x}^{2} - 58x + 8 = 0}$

$⟹−48x 2−58x+8=0$

$⟹\bold{24 {x}^{2} + 29x - 4 = 0}⟹24x </p><p>2+29x−4=0$

$⟹\bold{24 {x}^{2} + 32x - 3x - 4 = 0}$

⟹24x 2 +32x−3x−4=0

$⟹\bold{8x(3x + 4) - 1(3x + 4) = 0}$

⟹8x(3x+4)−1(3x+4)=0

$⟹\bold{(3x + 4)(8x - 1) = 0}$

⟹(3x+4)(8x−1)=0

$⟹\bold{3x + 4 = 0}⟹3x+4=0$

$⟹\bold{8x - 1 = 0}⟹8x−1=0$

$\bold{\boxed{\red{x = - \frac{4}{3} }}}$

x=−3/4
