A two-step equation requires you to perform just two steps in order to determine the unique solution to the linear equation. The first step is to identify the side of the equation with the unknown variable. Your goal will be to isolate this variable (or get it by itself). Consider the following example: 9 = 2x − 5.

Example 18.2. Solve the following word problems: a) Five times an unknown number is equal to 60. Find the number. Solution: We translate the problem to algebra: 5x = 60 5 x = 60. We solve this for x x : x = 60 5 = 12 x = 60 5 = 12. b) If 5 is subtracted from twice an unknown number, the difference is 13.

Summary. When writing linear equations (also called linear models) from word problems, you need to know what the x and y variables refer to, as well as what the slope and y-intercept are. Here are some tricks to help translate:. The x variable. Usually, you'll be asked to find an equation in terms of some factor. This will usually be whatever affects the output of the equation.

In Summary. Linear equations are a type of equation that has a linear relationship between two variables, and they can often be used to solve word problems. In order to solve a word problem involving a linear equation, you will need to identify the variables in the problem and determine the relationship between them.

Step-by-step application of linear equations to solve practical word problems: 1. The sum of two numbers is 25. One of the numbers exceeds the other by 9. Find the numbers. Let the number be x. Therefore, the two numbers are 8 and 17. 2.The difference between the two numbers is 48. The ratio of the two numbers is 7:3.

Let y = the number of sodas sold. 3. Write two equations. One equation will be related to the price and one equation will be related to the quantity (or number) of hot dogs and sodas sold. 1.50x + 0.50y = 78.50 (Equation related to cost) x + y = 87 (Equation related to the number sold) 4. Solve!

p=1/5 and q=1/11. Hence x−y =5 x − y = 5 and x +y = 11 x + y = 11, Solving these, x=8 km/hr and y=3km/hr. Question 8. A boat goes 24 km upstream and 28 km downstream in 6 hrs. It goes 30 km upstream and 21 km downstream in 6 hrs and 30 minutes. Find the speed of the boat in still water and also speed of the stream. Hint:
