y/-8(-8) multiply them together

$${\frac{{\mathtt{y}}}{-{\mathtt{8}}}}{\mathtt{\,\times\,}}-{\mathtt{8}} = {\mathtt{\,-\,}}{\frac{{\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{y}}}{-{\mathtt{8}}}}$$ then times both numbers by -1 to get $${\frac{{\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{y}}}{{\mathtt{8}}}}$$.

Then cancel the 8 to get y
