2x+y=44

y = 44-2x
x = 22 -y/2 Impossible to give actual values without another equation. |

Sure. I can give you an infinite number of answers. Which one do you want.

y could be any number from 0 to 44 as long as you stay in the positive… 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. |

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.
Or just set trip to 000.0 and drive back to gas station. |

To me it is a pretty simple math problem and it is boggling my mind that I can't figure out how to do it without setting an odometer 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. |

To me it is a pretty simple math problem and it is boggling my mind that I can't figure out how to do it without setting an odometer 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. |

Why are you applying algebra to a fucking google maps problem?

Your equation for your problem is like me asking you "if I ate 3 apples from my bowl of apples, how many apples are left in the bowl."

You have two guys, guy a and guy b.
Either guy a or guy b is named mark, the other's is jim. What is guy a's name? Same deal here, two variables but only one equation that can be used to solve (except in math the possible solutions to this problem are infinite, the name problem is limited to two possible solutions). |

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.
What you can do is get a graphing calculator to make a nifty line, since there is no single answer for either x or y in your equation. (don't forget to zoom out) |

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' |
