Solve

square root of c - 16 = 4 - square root of c

ANSWER:

square root of c - 16 = 4 - square root of c

Shift all c terms in one side constants to the other side,

For that add (square root of c ) to both sides of the equation.

==>
square root of c - 16 + square root of c = 4 - square root of c + squarert c

==> 2 ( square root of c ) -16 = 4

Add 16 on both sides of the equation,

==> 2 ( square root of c ) -16 + 16 = 4 + 16

==> 2 ( square root of c ) = 20

Divide both sides by 2

==> square root of c = 20/2

==> square root of c = 10

Here we want to solve for c, so square both sides of the equation,

==> (square root of c )^2= 10^2

==> c = 100

So the solution is, c = 100

Hope You understood.
