sqrt(7x+1)=2x-4

Solution

7 x + 1 = 2 x - 4

Solution

x = 5

Solution steps

7 x + 1 = 2 x - 4

Square both sides:

7 x + 1 = 4 x^{2} - 16 x + 16

7 x + 1 = 4 x^{2} - 16 x + 16

Solve

7 x + 1 = 4 x^{2} - 16 x + 16 : x = 5, x = \frac{3}{4}

x = 5, x = \frac{3}{4}

Verify Solutions:

x = 5

True

, x = \frac{3}{4}

False

The solution is

x = 5
