Substitute x = 6y + 21 into the first equation:-
6(6y+21) + 2y = 26
36y + 126 + 2y = 26
38y = -100
y = -2.63
x = 6(-2.63) + 21 = 5.22
answer (-2.63, 5.22) to nearest hundredth

-19 is a Yes
-30 a Yes
-21/10 = -2.1 so No
Distance from finish line can be computed by subtracting the amount he has ran from 3. Every minute he runs .5km, and we can use this to create a function to describe this instance.

The distance remaining is equivalent to the minutes multiplied by .5km for each minute subtracted from 3 which is the total distance.
