5 x + 4 = x - 4

x = \frac{21 + 185}{2}

Decimal Notation

x = 17.30073 \dots

Solution steps

5 x + 4 = x - 4

Remove square roots

5 x = x^{2} - 16 x + 64

Solve

5 x = x^{2} - 16 x + 64 : x = \frac{21 + 185}{2}, x = \frac{21 - 185}{2}

x = \frac{21 + 185}{2}, x = \frac{21 - 185}{2}

Verify Solutions:

x = \frac{21 + 185}{2}

True

, x = \frac{21 - 185}{2}

False

The solution is

x = \frac{21 + 185}{2}

u - 3 u + 2 = 0

2 x + 5 - 3 = x

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

y + y + 5 = 5

2 x + 3 - x + 2 = 2
