Question

How do you solve `-\frac { 3} { 4y - 8} + 1= \frac { 7} { y - 2}`?

Answer 1

`y=9 3/4`

Explanation:

`-3/(4y-8)+1=color(white)((4/4) * )7/(y-2)`

`color(white)(-3/(4y-8)+1)=(4/4) * 7/(y-2)=28/(4y-8)`

`color(white)(-3/(4y-8) + )1 =color(white)("xxxxxxxxxxxxxxx")(28+3)/(4y-8) =31/(4y-8)`

`color(white)("xxxxxx")4y-8 =31`

`color(white)("xxxxxx")4y=39`

`color(white)("xxxxxxx")y=39/4=9.75`
