Question

For certain simultaneos equations if
Dy= 6 and D= -3, what is the value of y​

Answer 1

Question:

• For certain simultaneos equations if $\sf{D_y}$ = 6 and D = -3, what is the value of y?

Solution:

We know that;

$\star \: {\underline{\boxed{\mathcal{\pmb{\quad y = \frac{D_y}{D} }}}}}$

Here we have,

• $\sf{D_y = 6}$

• $\sf{D = -3}$

Substituting values;

$:\implies\tt{y = \frac{D_y}{D} } \\ \\ :\implies\tt{y = \dfrac{6}{ - 3} } \\ \\ :\implies\tt{y = \frac{\cancel{6}}{\cancel{-3}}} \\ \\ :\implies{\boxed{ \sf{\red{y = - 2} }}} \: \bigstar$

Thus,

• The value of y is -2.
