Solution: Translating the problem into an algebraic equation gives: 2x − 5 = 13. We solve this for x. First, add 5 to both sides. 2x = 13 + 5, so that 2x = 18. Dividing by 2 gives x = 18 2 = 9. c) A number subtracted from 9 is equal to 2 times the number. Find the number. Solution: We translate the problem to algebra.
Linear Equation Word Problems
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.
Word Problems on Linear Equations
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.
Word Problems Linear Equations
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.
