Question

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

Answer 1

`0.2y+0.2x-8`

Explanation:

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

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

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

`(2)/(5)y-0.2y`

`=y\left((2)/(5)-0.2\right)`

`(2)/(5)-0.2=0.2`

`=0.2y`

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

`(1)/(5)x`

`=(1\cdot \:x)/(5)`

`=(x)/(5)`

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

`=0.2y+0.2x-8`
