Answer:
You aren't asked which variable to solve for.
If we're solving for x then
4x = 12y -8
x = 3y - (8/4)
If we're solving for y
-12y = -4x -6
12y = 4x +6
y = (x/3) + (1/2)
Step-by-step explanation:
40 miles an hour
60 [minutes] * 60 [seconds]= 3600
22.5[seconds for 1/4 of a mile]* 4[ one mile]= 90 [seconds per mile]
3600/90=40 [miles an hour]
