SOLUTION

TO DETERMINE

Find the solution to the equation p - 3 = 7 from the values (5, 7, 10). Show that the other values does not satisfy the equation.

EVALUATION

Here the given equation equation is

$\sf{p - 3 = 7 \: \: \: \: - - - - - (1)}$

We now solve for p

$\sf{p - 3 = 7 \: \: \: }$

$\sf{ \implies \: p = 3 + 7 \: }$

$\sf{ \implies \: p = 10 \: }$

So the required value of p = 10

CHECK

Here the given equation

$\sf{ \: p - 3 = 7 \: \: \: \: \: - - - (1) \: }$

1. Putting p = 5 in Equation (1) we get

$\sf{ \: 5 - 3 = 7 \: }$

$\sf{ \implies \: 2 = 7 \: }$

Which is absurd

So p = 5 is not a solution

2. Putting p = 7 in Equation 1 we get

$\sf{ \: 7 - 3 = 7 \: }$

$\sf{ \implies \: 4 = 7 \: }$

Which is absurd

So p = 7 is not a solution

3. Putting p = 10 in Equation 1 we get

$\sf{ \: 10 - 3 = 7 \: }$

$\sf{ \implies \: 7 = 7 \: }$

Which is true

So p = 10 is the required solution
