1.	Which of the following is the solution for 2x+4y=12?(a) x=2, y=2(b) x=1, y=0(c) x=3, y=1(d) x=-1, y=4The question was posed to me in final exam.My question is from Linear Equations Solutions in portion Linear Equations in Two Variables of Mathematics – Class 9
Answer» Correct answer is (a) x=2, y=2 The BEST I can explain: To find the solution of GIVEN equation, put the respective values of x and y in the given equation. If it SATISFIES the equation, it is the solution of given equation. Let’s check the values given in option a, which are x=2,y=2. 2(2) + 4(2) = 4 + 8 = 12 Which satisfies the equation 2x+4y=12 Hence, it is the solution of the given equation.
