0.2u=-0.5+3(0.8u+0.9)

0.2 u = - 0.5 + 3 (0.8 u + 0.9)

u = - 1

Solution steps

0.2 u = - 0.5 + 3 (0.8 u + 0.9)

Expand

- 0.5 + 3 (0.8 u + 0.9) : 2.4 u + 2.2

0.2 u = 2.4 u + 2.2

Move

2.4 u

to the left side

- 2.2 u = 2.2

Divide both sides by

- 2.2

u = - 1

x, \frac{1}{2} x - 3 y = 2

3 (x - 3) (x + 2) = 3 (x^{2} - 10)

\frac{3 n + 1}{6} = \frac{2 n - 1}{3}

14 = \frac{6 + z}{- 2}

y, 3 x^{3} - 2 x^{2} y + 5 x y = y - 3 x
