Question

The value of $X$ in $-19\times (4+(-2\left)\right)=-19\times 4+(-19)\times X$, is ____________

• A. $2$
• B. $-19$
• C. $4$
• D. $-2$

Answer 1

The correct option is D $-2$

We need to find value of $X$ in $(-19)\times (4+(-2\left)\right)=-19\times 4+(-19)\times X$
$\Rightarrow (-19)\times (4-2)=-19\times 4+(-19)\times X$
$\Rightarrow (-19)\times 2=-19\times 4+(-19)\times X$
$\Rightarrow -38=-76-19X$

$\Rightarrow X=\frac{38}{-19}=-2$
