sqrt(y^2-9)=9-y

Solution

y^{2} - 9 = 9 - y

Solution

y = 5

Solution steps

y^{2} - 9 = 9 - y

Square both sides:

y^{2} - 9 = 81 - 18 y + y^{2}

y^{2} - 9 = 81 - 18 y + y^{2}

Solve

y^{2} - 9 = 81 - 18 y + y^{2} : y = 5

y = 5

Verify Solutions:

y = 5

True

The solution is

y = 5

Popular Examples

sqrt((2x)/(5+x))=3x

\frac{2 x}{5 + x} = 3 x

sqrt(x+6)+sqrt(2-x)=4

x + 6 + 2 - x = 4

x^3=\sqrt[3]{x}

(x + 3)^{\frac{2}{3}} = 5

x - 7 = x - 7
