simplify 0.5x-2.5y+0.4x-1/2 y-2/5 x

simplify

0.5 x - 2.5 y + 0.4 x - \frac{1}{2} y - \frac{2}{5} x

- 3 y + \frac{1}{2} x

Solution steps

0.5 x - 2.5 y + 0.4 x - \frac{1}{2} y - \frac{2}{5} x

Group like terms

= 0.5 x + 0.4 x - 2.5 y - \frac{1}{2} y - \frac{2}{5} x

Add similar elements:

0.5 x + 0.4 x = 0.9 x

= 0.9 x - 2.5 y - \frac{1}{2} y - \frac{2}{5} x

Factor out common term

y

= 0.9 x + y (- 2.5 - \frac{1}{2}) - \frac{2}{5} x

Simplify

y (- 2.5 - \frac{1}{2}) : - y \cdot 3

= 0.9 x - y \cdot 3 - \frac{2}{5} x

0.9 = \frac{9}{10}

= \frac{9}{10} x - y \cdot 3 - \frac{2}{5} x

Group like terms

= - y \cdot 3 + \frac{9}{10} x - \frac{2}{5} x

Factor out common term

x

= - y \cdot 3 + x (\frac{9}{10} - \frac{2}{5})

\frac{9}{10} - \frac{2}{5} = \frac{1}{2}

= - y \cdot 3 + x \frac{1}{2}

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

\frac{1}{x - 2} + \frac{2}{x + 2}
