Solve the equation 3 x + 1 = 6 5 x − 1 . Options: A . &nbsp1 B . &nbsp2 C . &nbsp3 D . &nbsp9

Answer: Option A : A 3 x + 1 = 6 5 x − 1 On cross multiplication, we get ⇒ 3 ( 5 x − 1 ) = 6 ( x + 1 ) ⇒ 15 x − 3 = 6 x + 6 ⇒ 9 x = 9 ⇒ x = 1

Solve the equation 3x+1=65x−1.

Question

Solve the equation

\frac{3}{x + 1} = \frac{6}{5 x - 1}

Options:

A . 1

B . 2

C . 3

D . 9

Answer: Option A
:
A

\frac{3}{x + 1} = \frac{6}{5 x - 1}

On cross multiplication, we get

\Rightarrow 3 (5 x - 1) = 6 (x + 1) \Rightarrow 15 x - 3 = 6 x + 6 \Rightarrow 9 x = 9 \Rightarrow x = 1
