* To review how this works, in the system above, I could multiply the first equation by 2 to get the y-numbers to match, then add the resulting equations: If I plug into , I can solve for y: In some cases, the whole equation method isn't necessary, because you can just do a substitution. The first few problems will involve items (coins, stamps, tickets) with different prices.*If I have 6 tickets which cost each, the total cost is If I have 8 dimes, the total value is This is common sense, and is probably familiar to you from your experience with coins and buying things.

Examples, solutions, videos, and lessons to help Grade 8 students learn how to analyze and solve pairs of simultaneous linear equations. Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously. Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Systems of equations -word problem (coins) Example: A man has 14 coins in his pocket, all of which are dimes and quarters.

If the total value of his change is $2.75, how many dimes and how many quarters does he have?

Many of our resources are part of collections that are created by our various research projects.

Each collection has specific learning goals within the context of a larger subject area.

The first and third columns give the equations Multiply the second equation by 10 to clear decimals: Solve the equations by multiplying the first equation by 25 and subtracting it from the second: Then , so .

Thus, 42 of the .50 seats and 36 of the .50 seats were sold. A total of 300 tickets are sold, and the total receipts were 40. The first and third columns give the equations Multiply the first equation by 15 and subtract equations: Then There were 120 tickets sold for each and 180 tickets sold for each.There is no general rule for telling which of these things to do: You have to think about what the problem is telling you.A total of 78 seats for a concert are sold, producing a total revenue of 3.An investor buys a total of 360 shares of two stocks.The price of one stock is per share, while the price of the other stock is per share. How many shares of each stock did the investor buy?Trying to solve two equations each with the same two unknown variables?Take one of the equations and solve it for one of the variables.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.Other types of word problems using systems of equations include rate word problems and work word problems.Explains the concept of a value mixture problem and works this problem.
