Question

Is x=2 a solution of 2x-1=5

Answer 1

Answer:

no..

Step-by-step explanation:

if "x"=2

then L.H.S = R.H.S

L.H.S. = 2x - 1

= 2(2)-1

= 4-1=3

so L.H.S≠R.H.S

Hence x=2 is not solution .

Answer 2

Answer:

No it is not.

Step-by-step explanation:

p(x)= 2x-1

x=2 (given)

Substituting x=2 in p(x),

we get,

p(2)= 2*2-1

     = 4-1

     = 3

∴ This is not a solution for p(x) as it should be 3 rather than 5.
