8 x + 5 (8 x - 1) = - 1

x = \frac{1}{12}

Decimal Notation

x = 0.08333 \dots

Solution steps

8 x + 5 (8 x - 1) = - 1

Expand

5 (8 x - 1) : 40 x - 5

8 x + 40 x - 5 = - 1

Add similar elements:

8 x + 40 x = 48 x

48 x - 5 = - 1

Move

5

to the right side

48 x = 4

Divide both sides by

x = \frac{1}{12}

3^{4} \cdot 3^{2}

3 x + 3 = 2 x^{2}

\frac{22}{5} + \frac{11}{10}

(\frac{1}{2})^{3} + \frac{2}{3}

x^{3} + 7 x^{2} + 4 x - 12
