Problem 1 : One number is greater than thrice the other number by 2. If four times the smaller number exceeds the greater by 5, find the numbers. Problem 2 : The ratio of income of two persons is 1 : 2 and the ratio of their expenditure is 3 : 7. If the first person saves $2000 and the second person saves $3000, find the expenditure of each person. Problem 3 : Three chairs and two tables cost ...
For this lesson, we require students to use two variables (or more), making these problems a nice transition from single-variable problems to systems problems. Each of these systems is easily solved using substitution. Slide 1: Discuss with students some of the strategies involved in solving algebra problems.
Students will practice solving five-word problems about solving systems of equations using the substitution method. This would be a great activity for after a lesson on solving systems of equations.
In this article, we will explore how to solve systems of equations by substitution. We will provide step-by-step instructions and examples to help readers understand the concept. We will also discuss word problems that involve substitution method and answer frequently asked questions about the topic.
The Substitution Method One of the most common techniques for solving a linear system of equations is the substitution method. This method involves solving one equation for one variable and then substituting that expression into the second equation. By doing so, you reduce the problem to a single equation with one unknown that is easier to solve.
Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students learn how to solve systems of equations word problems using the elimination method and substitution method.
One popular method to solve these systems is substitution, which involves substituting one variable with an expression from another equation. This article aims to provide a comprehensive guide on using substitution to solve a system of equations, particularly focusing on word problems.
Problem 1 : One number is greater than thrice the other number by 2. If four times the smaller number exceeds the greater by 5, find the numbers. Solution : Let x be the smaller number and y be the greater number. Given : One number is greater than thrice the other number by 2. Then, we have y = 3x + 2 ----- (1)

TO FIND THE POINT OF INTERSECTION OF TWO LINES To find where two lines intersect we could graph them, but there is a faster, more accurate algebraic method called the equal values method or substitution method. This method may also be used to solve systems of equations in word problems. Also see the textbook, pages 169-70, 173-76, 242-43, and 248
