Problem 1026

Solve for the specified variable.

w²   + y² = z² for y

 

Solution:-

 

First isolate the term y² on the left side of the equation.

w²   + y² = z²

y² = z² – w²

Use the square root property and simplify. Let k be a nonnegative number. Then the solution to the equation x² = k are given by x = ±.

y² = z² – w²

y = ±.
