Question

Pls answer this question assap

Answer 1

`y = - (37)/(57)`

Explanation:

`(9 - 3y)/(1 - 9y) = (8)/(5)`

`(3(3y - y))/(1 - 9y) = (8)/(5)`

`3(3−y) * 5=(1−9y) * 8`

`45−15y=(1−9y) * 8`

`45−15y=8−72y`

`45+57y=8`

`57y=8−45`

`57y=−37`

`y = - (37)/(57)`

Hope it is helpful....

Answer 2

Explanation:

`(9-3y)/(1-9y) = (8)/(5)`

do cross multiplication

`5(9 - 3y) = 8(1 - 9y)\\45 - 15y = 8 - 72y\\45 - 8 = -72y + 15y\\37 = -57y\\(37)/(-57) = y`
