Question

Q.9. If Dx= -42,D= -3 and y = 6 2 points
then find x and Dy
​

Answer 1

Answer:

x= 14

Dy = -18

Step-by-step explanation:

Dx= -42

D= -3

therefore, x= -42/-3 = 14

now, y= 6

therefore, Dy = -3 * 6 = -18

Answer 2

Step-by-step explanation:

to find the value of x:-

apply the value of D in equation Dx

therefore,-3x=-42

x=-42/-3

x=14

now,value of D=-3 and value of y=62

the dy =-3×62

=-186
