So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.
The statistical question would be B.

-y=-2×+6
divided by negative 1 on both sides
y=2×-6
