Question

If Dx = -33, Dy = -66 and D = 11, what is the value of 'y'​

Answer 1

Given :-

• Dx = -33 , Dy = -66 , D = 11

To Find :-

• The value of y.

Solution :-

Applying Cramer's rule,

[ We have, Dx = -33 , Dy = -66 , D = 11 ]

$\tt \: \boxed{\tt \red{x = \frac{Dx}{D} \: \: \: \: \: or \: \: \: \: \: y = \frac{Dy}{D} }}$

[ Putting values ]

$↪ \tt \: x = \frac{ - 33}{11} \: \: \: \: \: or \: \: \: \: \: y = \frac{ - 66}{11}$

$↪ \tt \: x = \cancel \frac{ - 33}{11} \: \: \: \: \: or \: \: \: \: \: y = \cancel\frac{ - 66}{11}$

$↪ \tt \: \blue{ \boxed{ \tt{x = - 3 \: \: \: \: \: or \: \: \: \: \: y = - 6}}}$

Hence,

• The value of y is -6.
