Question

2/90 + 4/9x-4/9y-8/9x+2/3x

Answer 1

2/90 + 4/9x-4/9y-8/9x+2/3x  *90
2+40х-40у-80х+60х=2+20х-40у

Answer 2

To simplify the given expression $\frac{2}{90} + \frac{4}{9}x - \frac{4}{9}y - \frac{8}{9}x + \frac{2}{3}x$, we can combine like terms.

First, let's simplify the constants:

$$\frac{2}{90} = \frac{1}{45}$$

Next, let's simplify the terms with $x$:

$$\left(\frac{4}{9}x - \frac{8}{9}x + \frac{2}{3}x\right) = \left(\frac{4}{9} - \frac{8}{9} + \frac{2}{3}\right)x = \left(-\frac{2}{9} + \frac{2}{3}\right)x = \left(-\frac{2}{9} + \frac{6}{9}\right)x = \frac{4}{9}x$$

Now, the simplified expression is:

$$\frac{1}{45} + \frac{4}{9}x - \frac{4}{9}y$$
