Question

Solve 2x-1/2=5and also verify it

Answer 1

Answer:

Step-by-step explanation: cross multiplying we get:

2x-1 = 10

2x = 10+1

2x = 11

x = 11/2

x = 5.5

Answer 2

Hey Mate,

Given,

2x - 1/2 = 5

On transposing 1/2 from LHS to RHS, we get:-

=> 2x = 5 + 1/2

On transposing 2 from LHS to RHS, we get:-

=> x = ( 11/2 ) / 2

=> x = 11/4

Now on substituting the value of x as 11/4 in the equation 2x - 1/2 = 5, we get:-

2 ( 11/4 ) - 1/2 = 5

22/4 - 1/2 = 5

22/4 - 2/4 = 5

20/4 = 5

5 = 5

Since, LHS and RHS are both equal, x = 11/4 is the correct root for the equation 2x - 1/2 = 5.

Hope it Helps!
