Hello.
For p;
P - 3 1/5 = 7 1/3; Let's convert these into decimals.
P - 3.20 = 7.33
P = 10.5333~ is your first solution.
For y;
Y - 1 4/9 = 4 1/6; Convert these into decimals.
Y - 1.44~ = 4.167
Y = ~5.607 is your second solution.
For k;
K - 5 = 3/14;
K = 5 3/14 is your final solution.
I hope this helps!
