Answer:
Step-by-step explanation:
Solution to equation means by applying the given value of n or p in equation, the value on both sides of equation must be equal.
1) n+5=19 ; n=1
Substituting n with 1 in the equation,
1+5=19
6 = 19 This is not possible
So, n=1 is not a solution to the equation.
2) 7n+5=19 ; n=(-2)
7(-2)+5=19
(-14)+5=19
(-9) = 19
No, n=(-2) is not the solution.
3) 7n+5=19 ; n=2
7(2)+5=19
14+5=19
19=19
Yes, n=2 is a solution to the equatin.
4) 4p-3=13 ; p=(-4)
4(-4) -3=13
(-16) -3 = 13
(-19) = 13
No, p=(-4) is not a solution.
5) 4p - 3 = 19 ;p=0
4(0) - 3 = 19
0 - 3 = 19
(-3) = 19
No, p=0 is not a solution.
