ZanzabumX [31]
I would suggest looking up a converter chart, I don't know all of them but I can help with some.
For yards to feet you have to divide by 3 because there are 3 feet in a yard.
For lbs, it's 16 oz in a pound, so divide by 16.
For miles to yards you divide by 1760 because there are 1760 yards in a mile.
I hope this helps a little bit.

Ksenya-84 [330]

Answer:

\boxed{y = 3}

Step-by-step explanation:

=  > \frac{5 - 7y}{2 + 4y}  =  -  \frac{8}{7}  \\  \\  =  > 7(5 - 7y) =  - 8(2 + 4y) \\  \\  =  > (7 \times 5) - (7 \times 7y) = ( - 8 \times 2) + ( - 8 \times 4y) \\  \\  =  > 35 - 49y =  - 16  - 32y \\  \\  =  > 35 - 49y + 32y =  - 16 \\  \\  =  > 35 - 17y =  - 16 \\  \\  =  - 17y =  - 16 - 35 \\  \\  =  >   \cancel{- }17y =  \cancel{- } 51 \\  \\  =  > 17y = 51 \\  \\  =  > y =  \frac{51}{17}  \\  \\  =  > y = 3
