No, this is not a function because there is two x values there can't be two x values to be constant and true
-5/8b b=10
The new equation would look like this because we multiplied 8xb. 8 x b = 80
-5/80
Now if you divide -5 by 80 you get -0.0625
So -0.0625 is your answer
(x-2)/y = z
Multiply by y on both sides.
(x-2) = yz
Divide both sides by z.
(x-2)/z = y
