we know that
To find out the average speed divide the distance by the time
Let
s -----> average speed
d -----> the distance in feet
t ----> the time in minutes

we have


substitute
Simplify

If you're trying to solve for y
-2y = 8
Divide -2 to both sides

Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
Answer:
4) 2=4x-3y
5) 51=21x-3y
Step-by-step explanation:
I gave it my best shot, I used fraction busters to cancel out the fractions and then I used simple math and distributive property. Hope it helps.
