x-4=sqrt(7x+2)

Solution

x - 4 = 7 x + 2

Solution

x = 14

Solution steps

x - 4 = 7 x + 2

Square both sides:

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

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

Solve

x^{2} - 8 x + 16 = 7 x + 2 : x = 14, x = 1

x = 14, x = 1

Verify Solutions:

x = 14

True

, x = 1

False

The solution is

x = 14

Popular Examples

sqrt(x^2+2)=x+3

x^{2} + 2 = x + 3

3 = x^{\frac{1}{2}}

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

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

20 x - 11 = 7

sqrt(8x+33)+4=7

8 x + 33 + 4 = 7
