Worked-out word problems on linear equations with solutions explained step-by-step in different types of examples. There are several problems which involve relations among known and unknown numbers and can be put in the form of equations.
Word Problems & Linear Equations. Examples, solutions, videos, and worksheets to help Grade 7 and Grade 8 students learn how to graph a line specified by a linear function derived from a word problem. Graph a line specified by an initial value and a rate of change of a function and construct the linear function by interpreting the graph.
Linear Equation Word Problem. Problem stated in words are known as word problems. Solving word problem consists two steps. First step is translating the words of the problem into an algebraic equation. Second step is solving the equation. Let's see some examples. Example 1. If 7 is added to three times of a number, then the result is 28. Find ...
What Are Linear Equation Word Problems? A linear equation word problem involves a real-world situation or scenario that can be solved by setting up and solving linear equations. The equations that are used model the relationships between different quantities in the real-world scenario.
If you see the word rate, or even "per" or "each", it's a safe bet that a word problem is calling for a linear equation. There are a couple steps when translating from a word problem to a linear equation. Review them, then we'll work through an example. Find the y variable, or output.
Solve word problems leading to equations of the form px + q = r and p (x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.
