2 x - 5 = x + 9

x = \frac{21 + 185}{8}

Decimal Notation

x = 4.32518 \dots

Solution steps

2 x - 5 = x + 9

Square both sides:

4 x^{2} - 20 x + 25 = x + 9

4 x^{2} - 20 x + 25 = x + 9

Solve

4 x^{2} - 20 x + 25 = x + 9 : x = \frac{21 + 185}{8}, x = \frac{21 - 185}{8}

x = \frac{21 + 185}{8}, x = \frac{21 - 185}{8}

Verify Solutions:

x = \frac{21 + 185}{8}

True

, x = \frac{21 - 185}{8}

False

The solution is

x = \frac{21 + 185}{8}

(12 \cdot x)^{0.5} = 12

9 - 2 X = X^{2} + 9

y^{\frac{2}{3}} - \frac{1}{49} = 0

2 x - 1 + x = 8

- 13 = - 3 v^{- 0.8}
