Question

If Dx = 36, Dy=45 and D = 3 are the values of determinants for certain Simultaneous ous equation then find x and y

Answer 1

answer ::::::::

explaination

equation 1 and 2 both have D as common D value is 3 given

IF WE INPUT THE VALUES WE CAN FET ANSWER

1eq----D×X=36

3×X=36

3X=36 (TRANSPOSE RULE) BODMAS

X=36/3

X=12

2nd eq----D×Y=45

3×Y=45

3Y = 45 (TRANSPOSE RULE) BODMAS

Y=45/3

Y=15

~~~THE VALUES OF X AND Y IS 12 AND 15 ~~~
