1/3 x0.2+2/3 x0.4=30

\frac{1}{3} x \cdot 0.2 + \frac{2}{3} x \cdot 0.4 = 30

x = 90

Solution steps

\frac{1}{3} x \cdot 0.2 + \frac{2}{3} x \cdot 0.4 = 30

\frac{1}{3} x \cdot 0.2 = \frac{0.2}{3} x

\frac{2}{3} x \cdot 0.4 = \frac{0.8}{3} x

\frac{0.2}{3} x + \frac{0.8}{3} x = 30

Multiply both sides by

3

x = 90

2 x^{2} = - 6 + 8 x

- 5 > r - 630

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

(3 x + 2) (3 x + 5) - (3 x + 9) (3 x - 2) = x
