Question

Check whether the given value is a solution of the given equation or not.
$\frac{p}{2} + 2 = 5p - 7$
p=2 ​

Answer 1

Answer:

the answer is correct!

Do it with L.H.S AND R.H.S

answer is 3

Answer 2

Step-by-step explanation:

Method 1:

$\frac{p}{2} + 2 = 5p - 7$

$→ \frac{p + 4}{2} = 5p - 7$

$→p + 4 = 2(5p - 7)$

$→p + 4 = 10p - 14$

$→4 + 14 = 10p - p$

$→18 = 9p$

$→9p = 18$

$→p = \frac{18}{9}$

$→p = 2$

hence, p = 2 is the solution of the above equation.

Method 2:

Solve LHS and RHS by putting p = 2 :-

L.H.S. = p/2 + 2 ( put p = 2 )

= 2/2 +2

= 1+2

= 3

Now, R.H.S. = 5p -7 ( put p = 2)

= 5×2 - 7

= 10-7

= 3

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

hence, p = 2 is the solution of the above equation.
