Question

if D=7,Dx=-14,Dy=21 then find x and y(full answer)please ​

Answer 1

answer

If D = 7,Dx = 35 and Dy = 42 are the values of the determinants for certain simultaneous equations in x and y , then find the values of x and y .

Answer 2

Step-by-step explanation:

D=7;

Dx = -14 , Dy=21 ;

x = -14/7 = -2 ,

y = 21/7 = 3;

so value of x = -2 and y = 3..

hope it helps.
