5 x + 3 + 5 x + 2 = 21

x = \frac{14}{5}

Decimal Notation

x = 2.8

Solution steps

5 x + 3 + 5 x + 2 = 21

Remove square roots

5 x + 2 = 25 x^{2} - 180 x + 324

Solve

5 x + 2 = 25 x^{2} - 180 x + 324 : x = \frac{23}{5}, x = \frac{14}{5}

x = \frac{23}{5}, x = \frac{14}{5}

Verify Solutions:

x = \frac{23}{5}

False

, x = \frac{14}{5}

True

The solution is

x = \frac{14}{5}

3 t + 4 = 3

y^{2} - 8 = y - 2

x^{2} + 44 = 2 4 x - 1

h = (- 7536 t + k)^{\frac{2}{5}}

x^{2} + 3 x + 3 x^{2} + 3 x = 10
