sqrt(x+5)=7-x

Solution

x + 5 = 7 - x

Solution

x = 4

Solution steps

x + 5 = 7 - x

Square both sides:

x + 5 = 49 - 14 x + x^{2}

x + 5 = 49 - 14 x + x^{2}

Solve

x + 5 = 49 - 14 x + x^{2} : x = 11, x = 4

x = 11, x = 4

Verify Solutions:

x = 11

False

, x = 4

True

The solution is

x = 4

Popular Examples

x + 2 x = 8

sqrt(x)+1=sqrt(3x-3)

x + 1 = 3 x - 3

\frac{x}{2} = x

2=\sqrt[3]{4x-12}

x^{-1}=64sqrt(x)

x^{- 1} = 64 x
