Question #b4606

Answer 1

`y= -3/5x +9/5`

Explanation:

First of all, I'm not sure why you posted this question in chemistry.
Anyway, firstly you subtract `3x` from both sides

`cancel(color(red)(-3x))+cancel(3x) +5y= 9 color(red)(-3x)`

to get

`5y = 9-3x`

Then you divide both sides by `5`

`cancel(5)y/(cancel(color(red)(5))) = (9-3x)/(color(red)(5))`

to get

`y = (9-3x)/5`

Distribute the `5` to each term

`y= 9/(color(red)(5))-(3x)/(color(red)(5)`

Rearrange (not necessary) to obtain the answer:

`y= -3/5x +9/5`
