Transcript Ex 35, 3 (Substitution method) Solve the following pair of linear equations by the substitution and crossmultiplication methods 8x 5y = 9 3x 2y = 4 8x 5y = 9 3x 2y = 4 From (1) 8x 5y = 9 8x = 9 – 5y x = ((9 − 5𝑦))/8 Putting value of x in (2) 3x 2y = 4 3 (((9 − 5𝑦))/8) 2y = 4 (3(9 − 5𝑦))/8 2y = 4 (3(9 − 5𝑦) 8(2𝑦) )/8 = 4 3(9 – 5y) 8The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other Then you backsolve for the first variable Here is how it worksExercise 34 pair linear equations two variables chapter 3 NCERT solution Class 10 NCERT solutions that you will not find anywhere else!
