Question

For simultaneous equations in variables x and y, Dx = 49, Dy = -63, D = 7, find values of x and y.

Answer 1

Answer:

Dx = 30,Dy = 42 and D = 6 are the values of the determinants for certain simultaneous equations in x and y , then find the values of x and y .

Answer 2

Answer:

x =7 and y =9

DX= 49

x= 49/d

x= 7
