y could be any number from 0 to 44 as long as you stay in the

If you include negative numbers it could be any number.

Maybe my equation is wrong.

I drove from a gas station to my house (distance y). I then drive from my house to my job (distance x) and back to my house (distance x). I have 44 miles on my trip computer after doing that.

I want to figure out how many miles each leg is.

The equation is correct, but more information is needed to solve for your instance.




In order to define a single value to x, you need to know y, or vice-versa.

They probably just want you to put it into slope-intercept form.

y = -2x + 44

-2 is the pitch in "rise over run" of the line on the graph and 44 is where the line will intercept the y-axis.

Why not just set trip as 000.0 the next time you go to work.  When you get there you will know that leg distance.  You now have X.  Put it in equation and you will find Y.

Your equation is fine, but unless you know one of the values, you can't get the other one.  If it's 2 miles to the gas station, then it's 21 miles to work.  If it's 40 miles to the gas station, then it's 2 miles to work.  If it's 10 miles to the gas station, then it's 17 miles to work.  Any of these fits the equation, and could be true, but without knowing more, you can't get a single answer.

The issue is that without fixing either the distance from GS to H or from H to W, the numbers in the equation can change on the line I graphed above. You have to fix one of the two or you have to drive home from somewhere else and then drive to work and back to give us another equation.

That's how math works, and she doesn't give a shit.

Think of it this way... 2 of the trips could have been 10 miles (20 total) and the third trip could be 24 miles. That gets you to your total mileage. Or two of the trips could have been 5 miles (10 total) and the third trip would be 34 miles, also getting you to your 44 mile total. You can go on and on picking numbers that end up totaling 44 miles. It's not that your equation is unsolvable it's that there's more than a single correct answer.

I can make that equation work with an infinity of numbers.

Make either the X or the Y a definite, and the other will be able to be solved as a definite as well.

If you drive to work and back again tomorrow, then you'll have 2 equations, and a number for z:  2x+y=44, and 4x+y = z.  Then you can solve for a specific x and y.

You can't find the solution because there is no relationship defined between your trip to the gas station and your trip to work.  They are independent of one another; now if you said: the distance to work is three times the distance to the gas station (x=3y), you'd have a relationship between the two that makes the problem solvable.

You can't get a single answer for either x or y in your equation.

The rule of thumb in linear algebra is that you cannot solve for two variables when you only have one equation.

As others have noted, you can put in crapload of values for "x" and "y" and make this equation work, but there is no way to solve for a 'single answer'
