Question

Q. Answer the following questions :
1. For certain simultaneous equations, if
(1) D, = 12 and D = 4, what is the value of x?
(ii) D = - 3 and Dy = 6, what is the value of y?​

Answer 1

Step-by-step explanation:

(i) Dx = 12 D=4

x = Dx = 12

D 4

x = 3

(ii) D = -3 Dy = 6

y = Dy = 6

D -3

y = -2
