Answer:
k = 0
Step-by-step explanation:
<u>Explanation</u>:-
given straight line equation is k x+(k+1)y=2......(1)
The point A(2,2) lies on the equation is
substitute x = 2 and y=2
k(2) + (k+1)(2) =2
now simplify 2 k+2 k+2 = 2
subtracting '2' on both sides , we get solution is
4 k +2 -2 = 2-2
4 k =0
k = 0

3x-2=A(x-1)+Bx
3x-2=x(A+B)-A
A+B=3
-A=-2=>A=2
A+B=3=>2+B=3=>B=1
