1/21 x-4/7 = 2/3

\frac{1}{21} x - \frac{4}{7} = \frac{2}{3}

x = 26

Solution steps

\frac{1}{21} x - \frac{4}{7} = \frac{2}{3}

Move

\frac{4}{7}

to the right side

\frac{1}{21} x = \frac{26}{21}

Multiply both sides by

21

x = 26

4 x^{2} + 12 x + 5 = 0

\frac{3 - x}{8} = - 2

7 - 4 (8 - 3 x) < 7 (10 - x)

4 x^{2} + 24 x = - 43

2 x^{2} - 3 = x
