Write four solutions for the following equations: 2x y = 7.
Ex 4 2 2 Write Four Solutions For Each Of Following Exо Write four solutions for the following equation: 2x y = 7 mathematics. therefore, (0, 7) is a solution of this equation. therefore, (1, 5) is a solution of this equation. therefore, (−1, 9) is a solution of this equation. therefore, (2, 3) is a solution of this equation. concept: solution of a linear equation. Hence, four solutions for equation x = 4 y are (0, 0), (4, 1), (− 4, − 1), (8, 2). the provided answer is one of the various possible solutions. this question might have other solution too. Solution: (iii) we know that, a linear equation in two variables has infinitely many solutions. here, given equation is a linear equation in two variables x and y, so it has infinitely many solutions. ex 4.2 class 9 maths question 2. write four solutions for each of the following equations : (i) 2x y = 7, (ii) πx y = 9. (iii) x = 4y sol. Question 2 write four solutions for each of the following equations: i 2x y = 7 ii π x y = 9 iii x = 4y.
Write Four Solutions For Each Of The Following Equation 2x Y Solution: (iii) we know that, a linear equation in two variables has infinitely many solutions. here, given equation is a linear equation in two variables x and y, so it has infinitely many solutions. ex 4.2 class 9 maths question 2. write four solutions for each of the following equations : (i) 2x y = 7, (ii) πx y = 9. (iii) x = 4y sol. Question 2 write four solutions for each of the following equations: i 2x y = 7 ii π x y = 9 iii x = 4y. Click here👆to get an answer to your question ️ write four solutions for the following equation.2x y = 7. In the given linear equations, we can find any number of solutions by putting different values of x and obtain different values of y. i) 2x y = 7. changing the subject of the equation to y, and solving, we get, ∴ y = 7 2x . let us now take different values of x and substitute them in the given equation. for x = 0, we get y = 7 2 (0) ⇒.
