x+y = 4. and 10x +y , while the number wen interchange is 10y+x.
= 10y+x-(10x+ y)= 18.
Then 10y+x-10x-y=18
9y-9x=18
y-x=2 and x+y=4.
Solving simultaneously, 2y=6
Therefore, y=3 and x=1

Rorachy:
Change in demand is a movement along the same demand curve while a change in quantity demanded is a shift in a demand curve to an entirely new position.

Cardinal and ordinal utility are measures of utility.

Cardinal utility is propounded by neoclassical school of thought, cardinal utility has to do with the believe that utility can be measure and it is measured with utils.

While ordinal utility is propounded by modern economists which believe that utility cannot be measured, a consumer cannot measure the utility he derives from consuming a good, but it can be ranked.

You got it wrong. It is the other way. I mean between change in demand and change in quantity demanded.
