Question

(Pls i ur help)
If Dx=36 Dy=45 and D=3 are the values of the determinants of a certain simultaneous equations , then find the value of x and y
(It's a linear equation)

Answer 1

Answer:

x=6,y=9

Step-by-step explanation:

D=3

Dx=36

Dy=45

Substitute D value in Dx and Dy,then

Dx=36

3x=36

x=36/6

x=6

Dy=45

3y=45

y=45/5

y=9

Answer 2

Answer:x is 12

Y is 15

Step-by-step explanation:

Value of d is 3 so

3(x)=36

To get to 1x you need to divide by 3

X=12

Y same principle
