Answer 1

5p + 2 = 17

$<i>$Substitute values from 0 to ... till the equation gets satisfied

$<b><i><u>$
===>Continue Trials till error isn't obtained.

Substitute 0===> This is called trial
5(0)+2=17
0+2=17
2= 17
False
===> This is error

Substitute 1===> This is called trial
5(1)+2=17
5+2=17
7 = 17
False
===> This is error

Substitute 2===> This is called trial
5(2)+2=17
10+2=17
12 = 17
False
===> This is error

Substitute 3===> This is called trial
5(3)+2=17
15+2=17
17=17
LHS=RHS

So
$<b><u>$The value of p is 3
