Algebra - **Solving** Exponential **Equations** 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.

__Solving__ __linear__ __equations__ with __one__ __variable__ - YouTube (Note that we solve systems using matrices in the Matrices and __Solving__ Systems with Matrices section here.) “Systems of __equations__” just means that we are dealing with more than __one__ equation and __variable__. __Solving__ __linear__ __equations__ with __one__ __variable__ using addition and multiplication properties

__Solving__ __Linear__ __Equations__ in __One__ __Variable__ - University of 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* Dital Lesson.
