Give your answer as an improper fraction in its simplest form.

Answer 1

Answer:

x=32/7

Step-by-step explanation:

7x-2y=30

7x-2(1)=30                 bcos y=1

7x-2=30

7x=30+2

7x=32

x=32/7

since 7 is a prime number and 32 is not a multiple of 7, the answer given above is in the simplest form.
