Left at 12 p.m.
traveled 3 hrs and 5 min.....now it is 3:05 p.m.
stopped for fuel, 10 minutes....now it is 3:15 p.m.
drove for 1 hr and 20 min.....now its 4:35 p.m
There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate
Look at equation 1,

this can quite easily be manipulated to show

.
Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one

which can then be solved for x since there is only one variable

and then with our x solution we can work out our y solution by using the equation we manipulated

.
So the solution to these equations is x=-2 when y=6
