Verified by Toppr
We use trial and error method,
5p+2=17
Put, p=0
5(0)+2=17
=> 2
=17
Put, p=1
5(1)+2=17
=> 7
=17
Put, p=2
5(2)+2=17
=> 12
=17
Put, p=3
5(3)+2=17
=> 17=17
Hence p=3
Answer:
p = -6 is the solution of 7 - p = 13
Step-by-step explanation:
using trial and error method solve 7-p=13
Put p = 0
LHS = 7 - 0
= 7
≠ 13
So, p =1 is not solution
Put p = 1
LHS = 7 - 1
= 6
≠ 13
So, p =1 is not solution
Put p = -1
LHS = 7 -(-1)
= 8
≠ 13
So, p =-1 is not solution
Put p = -2
LHS = 7 -(-2)
= 9
≠ 13
So, p =-2 is not solution
Put p = -3
LHS = 7 -(-3)
= 10
≠ 13
So, p =-3 is not solution
Put p = -6
LHS = 7 -(-6)
= 13
= 13
So, p =-6 is a solution
