sqrt(7x+36)=x+4

Solution

7 x + 36 = x + 4

Solution

x = 4

Solution steps

7 x + 36 = x + 4

Square both sides:

7 x + 36 = x^{2} + 8 x + 16

7 x + 36 = x^{2} + 8 x + 16

Solve

7 x + 36 = x^{2} + 8 x + 16 : x = 4, x = - 5

x = 4, x = - 5

Verify Solutions:

x = 4

True

, x = - 5

False

The solution is

x = 4

Popular Examples

sqrt(4x-4)-sqrt(2-x)=1

4 x - 4 - 2 - x = 1

\frac{x}{5} = 2

4 = x - 4

sqrt(x-4)-sqrt(x-3)=-1

x - 4 - x - 3 = - 1

\frac{x}{4} = 1 + x
