Question

if 3x +5/2x +1 = 4/3​

Answer 1

After cross multiplication -:

3(3x +5) = 4 (2x + 1)

9x + 15 = 8x + 4

9x - 8x = 15 - 4

x = 11

Answer 2

Given:

• 3x +5/2x +1 = 4/3

Need to find:

• The value of x ?

Solution:

$:\implies\sf \dfrac{3x + 5}{2x + 1} = \dfrac{4}{3}$

$:\implies\sf 3(3x + 5) = 4(2x + 1)$

$:\implies\sf 9x + 15 = 8x + 14$

$:\implies\sf 9x - 8x = 4 - 15$

$:\implies{\boxed{\frak{\pink{x = -11}}}}\;\bigstar$
