make y the subject of the following :

Step-by-step explanation:
we first square both sides to eliminate the square root brackets..
(√(m(y+n)/y)²= p²
m(y+n)/y = p²
(my +mn)/y =p²
so we multiply both sides by y to eliminate the denominator,
(my+mn)/y*y =p²*y
my+mn = p²y
collecting like terms,we have:
mn= p²y-my
so we seperate the y on the right hand side from the rest to have
mn = y(p²-m)
so divided both sides by the value in the bracket on the right hand side we have..
mn/(p²-m)=y(p²-m)/(p²-m)
so we have,
y= mn/(p²-m)
Answer:
y = [tex]\frac{-mn}{m-p^2}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{\frac{m(y+n)}{y} }[/tex] = p ( square both sides )
[tex]\frac{m(y+n)}{y}[/tex] = p² ( multiply both sides by y )
m(y + n) = p²y ← distribute parenthesis on left side
my + mn = p²y ( subtract p²y from both sides )
my - p²y + mn = 0 ( subtract mn from both sides )
my - p²y = - mn ← factor out y from each term on the left side
y(m - p²) = - mn ← divide both sides by (m - p²)
y = [tex]\frac{-mn}{m-p^2}[/tex]
