Question

Q.1. A Select the appropriate alternative for each of the following (4 Ma 1) For a linear equation in variable x & y if Dx=49, D y=-63, D=7 then y = ? a)-0 b) 9 c) 7 d) -7​

Answer 1

Answer:

For simultaneous equations in variables x and y , Dx=49, Dy=-63, D=7 then what is x?

Given - D = 7 Dx = 49 Dy = -63 Value of x can be calculated by - x = Dx / D x = 49 / 7 x = 7 Value of y can be calculated by - y = Dy / D y = -63 / 7 y = -9
