Solution

90 - x = x

Solution

x = 9

Solution steps

90 - x = x

Square both sides:

90 - x = x^{2}

90 - x = x^{2}

Solve

90 - x = x^{2} : x = 9, x = - 10

x = 9, x = - 10

Verify Solutions:

x = 9

True

, x = - 10

False

The solution is

x = 9

Popular Examples

(x - 5)^{\frac{2}{3}} = 25

\sqrt[3]{x^3-3x^2+12}=x

sqrt(3x-22)=sqrt(-x+10)

3 x - 22 = - x + 10

x + 8 = x + 6

x = 9 x
