Algebra - Linear Equations There are several problems which involve relations among known and unknown numbers and can be put in the form of equations. Sum of two numbers = 25According to question, x x 9 = 25⇒ 2x 9 = 25⇒ 2x = 25 - 9 (transposing 9 to the R. S changes to -9) ⇒ 2x = 16⇒ 2x/2 = 16/2 (divide by 2 on both the sides) ⇒ x = 8Therefore, x 9 = 8 9 = 17Therefore, the two numbers are 8 and 17.2. A number is divided into two parts, such that one part is 10 more than the other. Try to follow the methods of solving word problems on linear equations and then observe the detailed instruction on the application of equations to solve the problems. Linear Equations. We'll start off the solving portion of this chapter by solving linear equations. A linear equation is any equation that can be written in the form.

Solving Simple Linear Equations - CliffsNotes You just need to type in the expressions on the left and rht side of the "=" sn. Algebraic equations are translated from complete English sentences. These equations can be solved. In fact, in order to successfully solve a word problem.

Word Problems on Linear Equations Equations in One Variable. In Example 3, you take the algebraic expression given in Example 1 and simplify it to review the process of simplification. With the help of equations in one variable, we have already practiced equations to solve some real life problems. Steps involved in solving a linear equation.

Aplusmath Math Flashcards - With the help of equations in one variable, we have already practiced equations to solve some real life problems. Solution: Let one part of the number be x Then the other part of the number = x 10The ratio of the two numbers is 5 : 3Therefore, (x 10)/x = 5/3⇒ 3(x 10) = 5x ⇒ 3x 30 = 5x⇒ 30 = 5x - 3x⇒ 30 = 2x ⇒ x = 30/2 ⇒ x = 15Therefore, x 10 = 15 10 = 25Therefore, the number = 25 15 = 40 The two parts are 15 and 25. Then Robert’s father’s age = 4x After 5 years, Robert’s age = x 5Father’s age = 4x 5According to the question, 4x 5 = 3(x 5) ⇒ 4x 5 = 3x 15 ⇒ 4x - 3x = 15 - 5 ⇒ x = 10⇒ 4x = 4 × 10 = 40 Robert’s present age is 10 years and that of his father’s age = 40 years.
