sqrt(8-x)=2x-1

Solution

8 - x = 2 x - 1

Solution

x = \frac{7}{4}

+1

Decimal

x = 1.75

Solution steps

8 - x = 2 x - 1

Square both sides:

8 - x = 4 x^{2} - 4 x + 1

8 - x = 4 x^{2} - 4 x + 1

Solve

8 - x = 4 x^{2} - 4 x + 1 : x = \frac{7}{4}, x = - 1

x = \frac{7}{4}, x = - 1

Verify Solutions:

x = \frac{7}{4}

True

, x = - 1

False

The solution is

x = \frac{7}{4}
