Then plug that into the other equation and solve for the variable.

Plug that value into either equation to get the value for the other variable.

The second train is going 85 mph for t time, or 85t. In other words, when do the two distances add up to the total distance, 800 miles. Now, we divide both sides by 160, and we get t = 5.

The first train is traveling at a rate of 75 mph, so the distance it covers in t time is 75t.

Ok, before we go, why don't we try that train problem, you know, just to show that we can. Another train leaves New York at the same time, traveling on a parallel track to Chicago at 85 mph. We're trying to find how much time it will take, or t.

traveling to New York, which is 800 miles away, at 75 mph.For others, it’s groaning, and frustration on where to even begin.Well, in this lesson we’re going to make Solving Linear Equation Word Problems manageable with easy to follow tricks and steps. Now, these steps might not seem all that remarkable, but once you see them in action I guarantee that writing equations from word problems and solving them will become like second nature! This is where you will write down all the information you’ve gleaned from the problem, and formulate a solution by writing an equation to model the situation, as Khan Academy accurately states.What’s the first thing that comes to mind when you hear the phrase Word problems?For some, it’s a chance to solve a real-world example, so there’s a level of excitement and sense of wonder.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more. So, it'll take you just over 11 weeks to get that bike. If you played 3 games and paid each for shoes, how much did you pay per game? We looked at simple examples, where the problem describes a number in terms of details about it, like the sum of twice a number and 52 is 174.Plus, get practice tests, quizzes, and personalized coaching to help you succeed. If we want to save 0, then our equation is 35w = 400. After you get the bike, you decide to have some fun. Then, we looked at problems that involve real-life scenarios, from loaning money to bowling. You also paid each for shoes, and there were three of you, so that's 3*3, or 9. In summary, we learned how to translate word problems in linear equations, or algebraic expressions that represent lines. I mean, two trains passing each other at 75 and 80 miles per hour won't see each other very long.If the equations are all linear, then you have a system of linear equations!To solve a system of equations, you need to figure out the variable values that solve all the equations involved.
