*Solving* basic *equations* & inequalities The *equations* are generally stated in words and it is for this reason we refer to these *problems* as word *problems*. If the two parts are in the ratio 5 : 3, find the number and the two parts. This topic covers - *Solving* *one*-*variable* *linear* *equations* - *Solving* *one*-*variable* *linear* inequalities

Word __Problems__ __Involving__ Systems of __Linear__ __Equations__ If the numerator is increased by 7 and the denominator is decreased by 1, the new number becomes 3/2. Solution: Let the numerator of a rational number = x Then the denominator of a rational number = x 3 When numerator is increased by 7, then new numerator = x 7 When denominator is decreased by 1, then new denominator = x 3 - 1 The new number formed = 3/2 According to the question, (x 7)/(x 3 - 1) = 3/2 ⇒ (x 7)/(x 2) = 3/2 ⇒ 2(x 7) = 3(x 2) ⇒ 2x 14 = 3x 6 ⇒ 3x - 2x = 14 - 6 ⇒ x = 8 The orinal number i.e., x/(x 3) = 8/(8 3) = 8/11 3. If the number formed by reversing the dits is less than the orinal number by 27, find the orinal number. Word *Problems* *Involving* Systems of *Linear* *Equations*. In this kind of *problem*.

Teaching *Linear* *Equations* - Math Videos 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*.

__Solving__ __Linear__ __Equations__ in __One__ __Variable__ - University of Worked-out word __problems__ on __linear__ __equations__ with solutions explained step-by-step in different types of examples. Solution: Then the other number = x 9Let the number be x. Therefore, x 4 = 2(x - 5 4) ⇒ x 4 = 2(x - 1) ⇒ x 4 = 2x - 2⇒ x 4 = 2x - 2⇒ x - 2x = -2 - 4⇒ -x = -6⇒ x = 6Therefore, Aaron’s present age = x - 5 = 6 - 5 = 1Therefore, present age of Ron = 6 years and present age of Aaron = 1 year.5. Then the other multiple of 5 will be x 5 and their sum = 55Therefore, x x 5 = 55⇒ 2x 5 = 55⇒ 2x = 55 - 5⇒ 2x = 50⇒ x = 50/2 ⇒ x = 25 Therefore, the multiples of 5, i.e., x 5 = 25 5 = 30Therefore, the two consecutive multiples of 5 whose sum is 55 are 25 and 30. The difference in the measures of two complementary angles is 12°. ⇒ 3x/5 - x/2 = 4⇒ (6x - 5x)/10 = 4⇒ x/10 = 4⇒ x = 40The required number is 40. *Solving* *Linear* *Equations* in *One* *Variable* Dital Lesson.
