Answer:
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
