Hi Tutor, can you please help me explain this? Thank you

Use the IS-LM-PC model to answer the following questions. In Japan, suppose there is a simultaneous increase in taxes and an increase in the money supply. Explain what kind of open market operations the Bank of Japan could use to increase the money supply? Graphically explain what short-run effect this particular policy mix will have on output and the interest rate. In addition, graphically explain what the resulting medium-run effect this policy mix will have on output, interest rate, and inflation rate.
