Solution:The LM curve shifts right/left when the money supply (real money balances) increases/decreases.
It also shifts left/right when money demand increases/decreases.
Nominal money is money value measured in terms of currency face value and real money is the value of the same money measured in terms of goods and services.
To clarify it more, the Real money value is one that is adjusted for inflation.
Nominal value or money is an unadjusted value.
