Question

For simultaneous equation in variables x and y, D = 2, Dx = 4, Dy = 8, then find the value of y.​

Answer 1

Y=4

Step-by-step explanation:

• Given that D=2
• Then $d(x) =4$  ,given D=2

                  $2(x)=4\\x=\frac{4}{2}$

                  $x=2$.

• This is made possible by simplest way of simplification.
• And given D(y) = 8
• In the same way we can able to find the value of y

              ⇒ $d(y)= 8$

                 $2(y)=8 \\y=\frac{8}{2} \\y=4$

• Therefore the value of y is the given simultaneous equations having variables as x and y is 4.
