sqrt(43-2y)=y-4

Solution

43 - 2 y = y - 4

Solution

y = 9

Solution steps

43 - 2 y = y - 4

Square both sides:

43 - 2 y = y^{2} - 8 y + 16

43 - 2 y = y^{2} - 8 y + 16

Solve

43 - 2 y = y^{2} - 8 y + 16 : y = 9, y = - 3

y = 9, y = - 3

Verify Solutions:

y = 9

True

, y = - 3

False

The solution is

y = 9
