Question

Solve and verify this question
2x-1/2=3

Answer 1

2x=3×2=6
therefore x=6/2=3

Answer 2

$\fbox {\bold{ANSWER}}$

2x - 1/2 = 3

2x = 3 + 1/2

2x = ( 6 + 1 ) / 2

2x = 7 / 2

x = 7 / 2× 2

x = 7 / 4

Now, putting the value of x in L. H. S. of the equation,

L. H. S. = 2x - 1/2

=> 2 ( 7 / 4 ) - 1/2

=> 7 / 2 - 1 / 2

=> 6 / 2

=> 3

= R. H. S.

Since, L. H. S. = R. H. S.

Hence, Verified.
