Question

For which equation n=8 is not a solution?

a) 3 n - 9= 15

b) n/2 + 11=15

c) 2n + 5 = 21

d) n/4 - 8 = -10​

Answer 1

Answer:

d)n/4 - 8 = - 10

Step-by-step explanation:

in d)

n/4 - 8 = - 10

LHS = n/4 - 8

=8/4 - 8

=2-8

=-6

RHS =-10

LHS is not equal to RHS

Therefore,n=8 is not a solution

Hope this helps

Answer 2

a)3n-9=15

=>3n=15+9

=>3n=24

=>n=24/3

=>n=8.

b)n/2+11=15

=>n/2=15-11

=>n/2=4

=>n=4×2

=>n=8

c)2n+5=21

=>2n=21-5

=>2n=16

=>n=16/2 =>n=8

d)n/4-8=-10

=>n/4=-10+8

=>n=-2×4

=>n=-8

Therefore, the value of question number d) gives -8.

So, number d) is odd.

Hope it is helpful for you.
