There is no b unfortunately
Find inverse of x+a
interchAnge
Inverse is
Now
- x-a=cx-d
- x-cx=a-d
- x(1-c)=a-d
- x=a-d/1-c
So
You can have any number according to this but
- c must not be 1
- a and d must not be equal .
- All three should belongs to integers set
Note:-
As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
Answer: 
Step-by-step explanation:
Y = 3bx - 7x
y = x(3b - 7)
Divide each side by 3b - 7 (assume that it is not zero).
Answer:
Let S be the sum,
S = 2 + 4 + 6 + ... + 2 (n - 2) + 2 (n - 1) + 2n
Reverse the order of terms:
S = 2n + 2 (n - 1) + 2 (n - 2) + ... + 6 + 4 + 2
Add up terms in the same positions, so that twice the sum is
2S = (2n + 2) + (2n + 2) + (2n + 2) + ... + (2n + 2)
or
2S = n (2n + 2)
Divide both sides by 2 to solve for S :
S = n (n + 1)
