Answer:

Step-by-step explanation:

X+1=> x=-1 , x+2=> x=-2

Substitute x=-1 in the equation , we will get,

2k-9 as remainder

Now substitute x=-2 in the equation , we will get , 5k-24 as remainder

Now it its given that sum of the remainder is 1 so,

(2k-9)+(5k-24)= 1

=>(2k-9)=-(5k-24)

=> 2k-9= -5k+24

=>2k+5k=24+9

=>7k=33

K=33/7 or k = 4*(5/7)

Megarox: Wait I did one thing wrong it is 8x so just multiply 8(-1) and 8(-2)

Megarox: Then do the same thing as give above like same method but the answer willdiffer it will be 4.5 , therefore k=4.5
