Question

if x minus 1 by 2 x is equal to 3 find the value of x square + 1 by 4 x square​

Answer 1

Answer:

Step-by-step explanation:

(x-1)/2x=3

thus by cross multiplication,

x-1=6x

-6x+x=1

x=1/5   ___(1)

(x^2+1)/4x^2

substituiting value of x

[(1/5)^2+1}/4(1/5)^2

[(1/25+1]/4*1/25

{(1+25)/25}/[4/25]

26/25*25/4

26/4

13/2=6.5

Answer 2

Answer:

(x-1)/2x=3

thus by cross multiplication,

x-1=6x

-6x+x=1

x=1/5   ___(1)

(x^2+1)/4x^2

substituiting value of x

[(1/5)^2+1}/4(1/5)^2

[(1/25+1]/4*1/25

{(1+25)/25}/[4/25]

26/25*25/4

26/4

13/2=6.5

Hope this helps.
