Question

solve this equation
4/n-1=2/n​

Answer 1

Answer:

=-1

Step-by-step explanation:

4/ n -1=2/n

4n=2n-2

4n-2n= -2

2n=-2

n =-2/2

n=-1

Answer 2

${\underbrace{Answer}}$

n = 2

${\underbrace{Step\ by\ step\ explanation }}$

$\sf{\frac{4}{n}}-1={\frac{2}{n}}$

$\sf\implies {{\frac{4}{n}}-{\frac{2}{n}}= 1}$

Here LCM = ' n '

$\sf{\implies {{\frac{4 -2}{n}}= 1}}$

$\sf{\implies {{\frac{2}{n}}= 1}}$

${\boxed{\implies {n = 2}}}$

${\underbrace{Verification}}$

Substitute the value of ' n ' in the given equation ...

${\frac{4}{2}}-1={\frac{2}{2}}$

$\implies{2-1=1}$

$\implies{1=1}$
