Question

Can someone pls help me / alguien me puede ayudar

Answer 1

The simplified expression is:

`(2)/(5)y+(1)/(5)x-0.2y-6+\left(-2\right)=0.2y+0.2x-8`

Explanation:

Given the expression

`(2)/(5)y+(1)/(5)x-0.2y-6+\left(-2\right)`

`\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a`

`=(2)/(5)y+(1)/(5)x-0.2y-6-2`

`\mathrm{Group\:like\:terms}`

`=(2)/(5)y-0.2y+(1)/(5)x-6-2`

Add similar elements

`=0.2y+(1)/(5)x-6-2`

`=0.2y+(x)/(5)-6-2`

`=0.2y+(x)/(5)-8`

`=0.2y+0.2x-8`

Thus, the simplified expression is:

`(2)/(5)y+(1)/(5)x-0.2y-6+\left(-2\right)=0.2y+0.2x-8`
