Answer:

−6x+7y = -1/8

Step-by-step explanation:

We need to evaluate −6x+7y when x=3/4 and y=5/8.

Put x=3/4 and y=5/8 in the given expression as follows :

[tex]=-6x+7y=-6\times \dfrac{3}{4}+7\times \dfrac{5}{8}\\\\=-3\times \dfrac{3}{2}+\dfrac{35}{8}\\\\=\dfrac{-9}{2}+\dfrac{35}{8}\\\\=\dfrac{-1}{8}[/tex]

So, the answer is (-1/8).
