Question

4,7p
$4 \times 7p = 28p$
​

Answer 1

Answer:

The value of p is 0

Step-by-step explanation:

4×7p = 28p

7p=28p/4

7p=7p

p = 0

Answer 2

Question:

$4\times7p=28p$ . Find the value of p

Given:

$4\times7p=28p$

To Find:

The value of p

Solution:

$4\times7p=28p\\\\\\28p=28p$

Since P is a variable the value of p varies in this equation it has infinite solutions

Proving:

$4\times7p=28p$

If p = 1

$4\times7p=28p\\\\\\28\times1=28\times1\\\\\\28=28\\\\\\\textsf{L.H.S=R.H.S}$

Therefore 1 is solution of p in $4\times7p=28p$

$4\times7p=28p$

If p = 2

$4\times7p=28p\\\\\\28\times2=28\times2\\\\\\56=56\\\\\\\textsf{L.H.S=R.H.S}$

Therefore 2 is solution of p in $4\times7p=28p$

$4\times7p=28p$

If p = 3

$4\times7p=28p\\\\\\28\times3=28\times3\\\\\\84=84\\\\\\\textsf{L.H.S=R.H.S}$

Therefore 3 is solution of p in $4\times7p=28p$

Answer:

Therefore it has infinite solutions
