For a complete lesson on systems of equations word problems, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve number and value word problems using a system of linear equations, as demonstrated in the following problem. Rodolfo has a total of 17 dimes and quarters worth $3.05. How many of each coin does he have? The two variables used in this problem are d, number of dimes, and q, number of quarters. Since Rodolfo has a total 17 dimes and quarters, one equation is d + q = 17. Since the value of his coins is $3.05, the other equation is 10d + 25q = 305. Note that since d represents the number of dimes, 10d represents the value of the dimes. And since q represents the number of quarters, 25q represents the value of the quarters.

This lesson covers wind and current problems. Students learn to solve wind and current word problems using a system of linear equations, as demonstrated in the following problem. Into a headwind, the plane flew 2000 miles in 5 hours. With a tailwind, the return trip took 4 hours. Find the speed of the plane in still air and the speed of the wind. The two variables used in this problem are p, the speed of the plane in still air, and w, the speed of the wind. So the speed of the plane with a tailwind can be represented as p + w, and the speed of the plane against a headwind can be represented as p -- w. Note that this problem requires a chart to organize the information. The chart is based on the formula rate times time = distance. The chart is then used to set up the two equations.
