Question

-4/5y - 3 = 9 what is y?

Answer 1

`y=-15`

Explanation:

In order to find the value of a variable we must isolate it from the rest of the equation.


`-(4)/(5)y-3=9`
Add 3 on both sides:

`-3+3=0`

`9+3=12`

`-(4)/(5) y=12`
Multiply both sides by 5:

`12*5=60`

`-4y=60`
Divide both sides by -4:

`-4y/-4=y`

`60/-4=-15`

`y=-15`

Therefore the value of y in this equation is "-15."

I hope this helps.

Answer 2

y = -15

Explanation:

-4/5 y - 3 = 9

-4/5 y = 12

y = 12 × (-5/4)

y = -15
