Evaluate −6x+7y when x=34 and y=58. Write your answer as a fraction in simplest form.

-6 3/4 + 7 5/8

Answer 1

−6x+7y = -1/8

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 :

`=-6x+7y=-6* (3)/(4)+7* (5)/(8)\\\\=-3* (3)/(2)+(35)/(8)\\\\=(-9)/(2)+(35)/(8)\\\\=(-1)/(8)`

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