a(y-1)/1+y

Step-by-step explanation:

Given the expression y = a + p/a-p

yo are to make P the subject of the formula:

Step 1:  Cross multiply

y = a + p/a-p

y(a-p) = a+p

Step 2: open the bracket

ya - yp = a+ p

Step 3: Collect the like terms

ya - a  = p+ yp

ya - a= p(1+y)

a(y-1) = p(1+y)

Step 4: Divide both sides by 1+y

a(y-1)/1+y = p(1+y)/1+y

a(y-1)/1+y = p

p =a(y-1)/1+y

Hence the required solution is p = a(y-1)/1+y
